The string.slice() is an inbuilt method in javascript which is used to return a part or slice of the given input string.
Syntax: 
 

string.slice(startingindex, endingindex)

Parameter: This method uses two-parameter startingindex( from which index, the string should be started) and endingindex (before which index, the string should be included).
Return Values: It returns a part or a slice of the given input string.
JavaScript code to show the working of the string.slice() method: 
Code #1: 
 

javascript




<script>                   
  
   // Taking a string as input.
   var A = 'Ram is going to school';
    
   // Calling of slice() function.
   b = A.slice(0, 5);
 
   // Here starting index is 1 given
   // and ending index is not given to it so
   // it takes to the end of the string 
   c = A.slice(1);
    
   // Here endingindex is -1 i.e, second last character
   // of the given string.
   d = A.slice(3, -1);
   e = A.slice(6);
   document.write(b +"<br>");
   document.write(c +"<br>");
   document.write(d +"<br>");
