replace() using strings in JS

<!DOCTYPE html>

<html>

<head>

//replace will basically search for the given word and replace it with required word

var str= "This a great platform for learning html , css and javascript!!!";

var b= str.replace("html" , "cool html ");

console.log(b);

var newstr= "This a great platform for learning great html , css and javascript!!!";

var x=newstr.replace("great","GREAT");

document.write(x);

document.write("<br><br><br>")

/*note that it has only repaced one "great" expression.

To replace it everywhere we need to use global variables*/

var y=newstr.replace( /great/g , "HIGHLY AWESOME");

document.write(y);

</script>
