How do I hide my class element when data-reviews is less than 5?

I have tried using basic JavaScript when data-reviews="2" and it worked, but what I need is when data-reviews is less than 5 or any specific number, the whole <span> section should be hidden. I need assistance on this. I am trying to achieve the same outcome but I want to hide this, when data reviews has < 5.
<div class="collection-list-badge">
<span class="stamped-product-reviews-badge" data-id="5649263493270" style="display:block;">
<span class="stamped-badge" data-rating="5.0" data-lang="en" aria-label="Rated 5.0 out 42reviews"></span>
</span>
<span class="stamped-badge-caption" data-reviews="42" data-rating="5.0" data-label="reviews" aria-label="42 reviews" data-version="2">42</span>
</div>

Loop over the badge elements. For each collection badge select the review element. Parse the data-reviews attribute with parseInt. Check if the review is less than 5. If so, remove the collection badge element.
const collectionListBadges = document.querySelectorAll('.collection-list-badge');
for (const collectionListBadge of collectionListBadges) {
const reviewsElement = collectionListBadge.querySelector('[data-reviews]');
const amountOfReviews = parseInt(reviewsElement.getAttribute('data-reviews'));
if (amountOfReviews < 5) {
collectionListBadge.remove();
}
}
<div class="collection-list-badge">
<span class="stamped-product-reviews-badge" data-id="5649263493270" style="display:block;">
<span class="stamped-badge" data-rating="5.0" data-lang="en" aria-label="Rated 5.0 out 42reviews"></span>
</span>
<span class="stamped-badge-caption" data-reviews="42" data-rating="5.0" data-label="reviews" aria-label="42 reviews" data-version="2">42</span>
</div>
<div class="collection-list-badge">
<span class="stamped-product-reviews-badge" data-id="5649263493270" style="display:block;">
<span class="stamped-badge" data-rating="4.0" data-lang="en" aria-label="Rated 4.0 out 38reviews"></span>
</span>
<span class="stamped-badge-caption" data-reviews="4" data-rating="4.0" data-label="reviews" aria-label="38 reviews" data-version="2">4</span>
</div>

add 'ids' to checkbox elems from ~ sibling element innerText val

Goal: I am trying to iterate through a series of checkboxes, and add an "id" to each elem with the value of the checkboxes sibling text value. i.e. inner text of .k-in
Recent attempt:
function addSelectors() {
const checks = document.querySelectorAll('.k-treeview-lines input[type="checkbox"]');
[].forEach.call(checks, function (checks) {
let knn = document.querySelectorAll('.k-treeview-lines input[type="checkbox"] ~ .k-in');
checks.id = knn.innerText;
});
}
HTML is a series of the below:
<div class="k-mid">
<span class="k-checkbox-wrapper" role="presentation">
<input type="checkbox" tabindex="-1" id="undefined"
class="k-checkbox"><-- id here
<span class="k-checkbox-label checkbox-span"></span>
</span>
<span class="k-in">I want this</span><---- this text
</div>
Do not want to load jQuery...

function addSelectors() {
const checks = document.querySelectorAll(
'.k-treeview-lines input[type="checkbox"]'
);
checks.forEach(function (checkbox) {
const textVal = checkbox.parentElement.nextElementSibling.innerText;
checkbox.setAttribute("id", textVal);
});
}
addSelectors();
<div class="k-treeview-lines">
<div class="k-mid">
<span class="k-checkbox-wrapper" role="presentation">
<input
type="checkbox"
tabindex="-1"
id="undefined"
class="k-checkbox"
/>
<span class="k-checkbox-label checkbox-span"></span>
</span>
<span class="k-in">tempID</span>
</div>
</div>

The item you are requesting is not actually the sibling, they don't share the same parent.
You could do something like this:
function addSelectors() {
const checks = document.querySelectorAll('input[type="checkbox"]');
checks.forEach(c => {
c.id = c.parentNode.nextElementSibling.innerText;
});
}
addSelectors();
<div class="k-mid">
<span class="k-checkbox-wrapper" role="presentation">
<input type="checkbox" tabindex="-1" id="undefined" class="k-checkbox">
<span class="k-checkbox-label checkbox-span"></span>
</span>
<span class="k-in">I want this</span>
</div>

How to remove specific content with javascript

I have this element appearing on page:
<span class="vc_gitem-post-category-name">Front</span>
<span class="vc_gitem-post-category-name">Category 1</span>
<span class="vc_gitem-post-category-name">Category 2</span>
<span class="vc_gitem-post-category-name">Front</span>
<span class="vc_gitem-post-category-name">Category 3</span>
<span class="vc_gitem-post-category-name">Front</span>
I need to remove every instance of this:
<span class="vc_gitem-post-category-name">Front</span>
There are other categories also listed in the same way and I need that particular category element (span + text) to be removed. There is currently no possibility of adding any specific class or id to the element so it has to be removed in other way.

Use the class name in your selector so you can loop over the elements.
Then, check the contents of each entry, and if a match is found, wrap the current ref in a jQuery object and use remove, which will remove it from the DOM.
jQuery('span.vc_gitem-post-category-name').each(function() {
var text = this.innerHTML;
if (text === 'Front') {
jQuery(this).remove();
}
});

You can acheive this with javascript as well:
https://jsfiddle.net/dhanrajv/av1twkqs/
var byClassName = document.querySelectorAll('span.vc_gitem-post-category-name');
for(var i=byClassName.length;i--;){
if(byClassName[i].innerHTML === 'Front') {
window.document.body.removeChild(byClassName[i]);
}
}
<span class="vc_gitem-post-category-name">Front</span>
<span class="vc_gitem-post-category-name">Category 1</span>
<span class="vc_gitem-post-category-name">Category 2</span>
<span class="vc_gitem-post-category-name">Front</span>
<span class="vc_gitem-post-category-name">Category 3</span>
<span class="vc_gitem-post-category-name">Front</span>

How to get id of anchor tag, regardless of where it is in hierarchy?

I want to get the id/class/both of the anchor tag, regardless of where it falls in the tag hierarchy. Example below is strange but realistic for my purposes because our website is accessed through a CMS that I have no control over. If people add multiple levels of formatting at different times, the CMS likes to add new span's...
So, having the live with the above facts, I want to pin down specific anchor tags by their id/class/both, but I don't always know where they will be located in the tag drill-down.
<div id="div_id_A" class="div_class_A">
<div class="div_class_A">
<a href="#" id="anchor_id_A" class="anchor_class_A">
<span class="span_class_A">
<span id="span_id_B">
<span id="span_id_C" class="span_class_C">
<p>
Click Me
</p>
</span>
</span>
</span>
</a>
</div>
</div>
I have started off like such,
var dataLayer = dataLayer || [];
document.addEventListener('click', function(event) {
var telm = event.target.parentNode.className;
var delm = 'anchor_id_A';
console.log(telm);
if (telm == delm) {
dataLayer.push({
'youClicked': telm
});
console.log(dataLayer);
};
});
*WHERE: telm = target element; delm = desired element.
To clarify. I am specifying anchor for a reason, it is not simply for the example. As I am restricted by our CMS, I can't go in and add markup to pre-defined code (i.e. template), but I do need to know what link was clicked as exactly as possible (for Google Analytics), so that I can track down what users are ignoring, not seeing, or prefering.

You can navigate up the hierarchy until you reach the anchor element, then just read its ID.
See here:
var dataLayer = dataLayer || [];
document.addEventListener('click', function(event) {
var el = event.target;
while (el.parentElement && el.tagName != 'A') {
el = el.parentElement;
}
dataLayer.push({
'youClicked': el
});
console.log(dataLayer);
alert(el.id);
});
<div id="div_id_A" class="div_class_A">
<div class="div_class_A">
<a href="#" id="anchor_id_A" class="anchor_class_A">
<span class="span_class_A">
<span id="span_id_B">
<span id="span_id_C" class="span_class_C">
<p>Click Me</p>
</span>
</span>
</span>
</a>
</div>
</div>

What you're trying to achieve, is probably something like this :
var dataLayer = [];
document.addEventListener('click', function(event) {
var needle = 'anchor_class_A'; // The class of the element you're looking for
var closest = event.target.closest("." + needle);
if(closest && closest.id) {
dataLayer.push({
'youClicked': closest.id
});
alert(JSON.stringify(dataLayer, null, '\t'));
}
});
<div id="div_id_A" class="div_class_A">
<div class="div_class_A">
<a href="#" id="anchor_id_A" class="anchor_class_A">
<span class="span_class_A">
<span id="span_id_B">
<span id="span_id_C" class="span_class_C">
<p class="clicker">
Click Me
</p>
</span>
</span>
</span>
</a>
</div>
<div class="div_class_A">
<a href="#" id="anchor_id_X" class="anchor_class_A">
<span class="span_class_A">
<span id="span_id_Y">
<span id="span_id_Z" class="span_class_C">
<p class="clicker">
Click Me
</p>
</span>
</span>
</span>
</a>
</div>
</div>

Wrong result after compare select.val() and span.text()

I have a folowing problem.
On click button Filter I want get entries with selected city.
SO forbid me write big code, so I show only div with data. I think you can add select with options, if you want.
(Select id = "cityFilter" , options: Dnepr, Kharkiv, Lviv)
HTML:
<div id="data">
<div>
<a class="userEmail" href="#">user1#domain.ua </a>
<span> user1 </span>
<span> Dnepr </span>
<span><input type = "button" value = "x" /></span>
</div>
<div>
<a class="userEmail" href="#">user2#domain.ua </a>
<span> user2 </span>
<span> Kharkiv </span>
<span><input type = "button" value = "x" /></span>
</div>
<div>
<a class="userEmail" href="#"> user3#domain.ua </a>
<span> user3 </span>
<span> Lviv </span>
<span><input type = "button" value = "x" /></span>
</div>
<div>
<a class="userEmail" href="#"> user4#domain.ua </a>
<span> user4 </span>
<span> Dnepr </span>
<span><input type = "button" value = "x" /></span>
</div>
<div>
<a class="userEmail" href="#"> user5#domain.ua </a>
<span> user5 </span>
<span> Lviv </span>
<span><input type = "button" value = "x" /></span>
</div>
</div>
cityFilter.js (The description of the code in comments):
$(function() {
//click on button
$('body > input').on('click', function() {
//get selected value
var cityFilter = $('#cityFilter').val();
//sort out spans which contains city names
$('#data > div > a + span + span').each(function() {
//for check the received value
console.log($(this).text());
//compare selected value and span text
if ($(this).text() != cityFilter) {
console.log('true');
}
});
});
});
I got all true. Where is the problem ?

your spans have leading and trailing spaces
i.e. " abc " != "abc"
try the following instead:
if ($(this).text().trim() != cityFilter) {
console.log('true');
}
