toCharArray() //get char array of a String

charAt(int x) //get a char at the specific index

length() //string length

var provides functional scoping but not block scoping. var allow to log the variable without declaring it though it shows undefined.
let provides functional scoping as well as block scoping.
const provies functional scoping as well as block scoping but you cannot reassign value to a const type variable.

let and const will not allow you the log the variable without declaring it.

None of the string methods modify this – they always return fresh strings.

charAt(pos: number): string ^ES1

Returns the character at index pos, as a string (JavaScript does not have a datatype for characters). str[i] is equivalent to str.charAt(i) and more concise (caveat: may not work on old engines).

	if(len1 < len2){
