i am facing issue when using backticks , The browser show it string,
example:
<h2>${item.title}</h2>
Output:
${item.title}

I don't know where to using this. but simply you can use backticks like this.
In HTML
<div id="title"></div>
In Javascript
const titleTag = `<h2>${item.title}</h2>`;
const element = document.getElementById("title");
element.innerHTML = titleTag;

I'm trying to import the Observable class and the interval method and it's giving it to the terminal

You don't need to use the Observable prefix. So just remove it:
let time = interval(500);

This regular expression is not working as expected.Please suggest other way to validate this regular expression in javascript.
var patt = new RegExp('^(PK\d{2}[A-Z]{4}\d{16})|(\d{9,20})$');
patt.test('PK12FKIE1234567890123456');
You need put both patterns inside a single group so that the anchors should apply to both.
var patt = /^(?:(PK\d{2}[A-Z]{4}\d{16})|(\d{9,20}))$/;

I'm trying to learn regex. I need to find +46 and replace it with 0. I've been racking my brain but I can't figure out the correct syntax. I'm trying to do it in JS with replace.
Any takers?
Use .replace():
"987654321+46".replace("+46", "0")

I'm trying to have my numbers in a format that is easier for the user to read.
Eg. Instead of: 12349568483, it would be: 12 349 568 483.
I was wondering if there is a simple way to do this?
var a = "12349568483";
a = a.split('').reverse().join('').replace(/([0-9]{3})/g, "$1 ").split('').reverse().join('');
