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.
