String Methods:

JavaScript provides a lot of string methods which help in working with strings. Some of them are:

  • charAt(): It provides the char value present at the specified index.
  • charCodeAt(): It provides the Unicode value of a character present at the specified index.
  • concat(): It provides a combination of two or more strings.
  • indexOf(): It provides the position of a char value present in the given string.
  • lastIndexOf(): It provides the position of a char value present in the given string by searching a character from the last position.
  • search(): It searches a specified regular expression in a given string and returns its position if a match occurs.
  • match(): It searches a specified regular expression in a given string and returns that regular expression if a match occurs.
  • replace(): It replaces a given string with the specified replacement.
  • substr(): It is used to fetch the part of the given string on the basis of the specified starting position and length.
  • substring(): It is used to fetch the part of the given string on the basis of the specified index.
  • slice(): It is used to fetch the part of the given string. It allows us to assign positive as well negative index.
  • toLowerCase(): It converts the given string into lowercase letter.
  • toLocaleLowerCase(): It converts the given string into lowercase letter on the basis of host?s current locale.
  • toUpperCase(): It converts the given string into uppercase letter.
  • toLocaleUpperCase(): It converts the given string into uppercase letter on the basis of host?s current locale.
  • split(): It splits a string into substring array, then returns that newly created array.
  • trim(): It trims the white space from the left and right side of the string.
Examaple 1:
var x ="Adarsh ";
var y ="Chaudhary";
var z = x.concat(y);
Here z will store Adarsh Chaudhary.
Examaple 2:
var x = "Adarsh Chaudhary";
var z = x.toUpperCase();
Here z will store ADARSH CHAUDHARY.
Examaple 3:
var x = " Adarsh ";
var z = x.trim();
Here z will store Adarsh.

Try the following example in the editor below.

You are given a string S, you have to print the string after combining it with it’s UPPERCASE form.

Sample Input:
