my replace function only replace one character.
My Code example
const string = "What,Yo,Yes"
string.replace(","," ")
Console
"What Yo,Yes"

Something like this:
const string = "What,Yo,Yes";
console.log(string.replace(/,/g," "));
Alternatively, you can use replaceAll, like this:
const string = "What,Yo,Yes";
console.log(string.replaceAll(","," "));

I have a string field 01/01/1986 and I am using replace method to replace all occurrence of / with -
var test= '01/01/1986';
test.replace('//g','-')
but it does't give desire result. Any pointer would be helpful.

You just have a couple issues: don't put the regex in quotes. That turns it into a string instead of a regex and looks for that literal string. Then use \/ to escape the /:
var test= '01/01/1986';
console.log(test.replace(/\//g,'-'))

A quick way is to use split and join.
var test= '01/01/1986';
var result = test.split('/').join('-');
console.log(result);
Note too that you need to save the result. The original string itself will never be modified.

Javascript and regex: split string and keep the separator

If I have this string: "MyStringToForSplitting" and I want to split it by this word "ring".
If I do this: "MyStringToForSplitting".split('ring')
I will get array that contains this elements:
MyS
ToForSplitting
I can't figure out best way to split it and include 'ring' in resulting array like this:
1.MyS
2.ring
3.ForSplitting

You can use regex and capture the split pattern:
console.log("MyStringToForSplitting".split(/(ring)/));
var s = "ring";
var p = new RegExp("(" + s + ")")
console.log("MyStringForSplitting".split(p))

I want to replace all the words that match with a variable in a string, but it doesn't work. I use this code:
var findStr = "hello hi, test, hi";
var textSearch = "hi";
findStr = findStr.replace(textSearch,'<span>'+textSearch+'</span>');
It has to change the color of hi but only the first hi changes, the second one doesn't.

The replace method is what you're looking for.
For example: someString.replace("String you want to replace", "with this string")

I am trying to extract a string from within a larger string where i need to get the value only inside the brackets.
var str = 'ajay kumar (68766)';

Try this:
var str = 'ajay kumar (68766)';
str = str.slice(str.indexOf('(')+1, str.indexOf(')'));

How about using a regular expression?
var str = 'ajay kumar (68766)';
var output = str.replace(/^[\s\S]*?\((\d+)\)[\s\S]*?$/, '$1');
