hey would love to have a take from a more experienced coder about this.
Would appreciate if you could give it to me in the below code format, thanks a lot
You could use document.querySelectorAll.
This returns a Node List, to convert that to an Array, you could do
const elements = [...document.querySelectorAll(".my-selector")];
That's called Vanilla Javascript
An example
var myArray = document.getElementsByClassName('myClass')
myArray will be a HTMLCollection

How to get element by innerText
(18 answers)
Closed 4 months ago.
Using jQuery, if I want to grab an element using the text inside it, I can do:
$( "div:contains('John went to the shop')" )
I can find loop functions and the use of XPATH, but nothing similar to jQuery.
Is there something simple like this for querySelector or equivalent methods?

// Then Loop Through it ....

You can get value with selector too.
document.querySelector("{SELECTOR}").innerHTML;
You can copy any selector with right click from Chrome Developer Console.

It seems like these two statements produce the same output.
console.log(myId)
console.log(document.getElementById('myId'))
<div id="myId">Hello World!</div>
Q: Is it safe to use myId instead of document.getElementById('myId')

document.getElementById vs jQuery $()

Can somebody explain to me what the difference is between these two examples:
var obj = getElementById("id1"); // without jQuery
var obj = $("#id1"); // with jQuery
Is the returned value in both cases the same object?
getElementById() returns a DOM element only, $("#id1") returns a jQuery object containing DOM element(s).
