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

Syntax:

string.slice(startingIndex, endingIndex)

Parameters: This method uses two parameters. This method does not change the original string.

startingIndex: from which index, the extraction of the string should be started.
endingIndex: before which index, the extraction of the string should be included.

Return Values: It returns a part or a slice of the given input string.

Example 1: Here is the basic example of a string.slice() method.

javascript

let A = 'Geeks for Geeks';
b = A.slice(0, 5);
c = A.slice(6, 9);
d = A.slice(10);
 
console.log(b);
console.log(c);
console.log(d);

Output:

Geeks
for
Geeks

Example 2: Here is another example of the above-explained method.

javascript

let A = 'Ram is going to school';
 
// Calling of slice() Method
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);
console.log(b);
console.log(c);
console.log(d);
console.log(e);

Example 3: Here is an example of the slice() method.

javascript

let A = 'Geeks for Geeks';
 
// Calling of slice() Method
// Here starting index is -1 given
b = A.slice(-1, 5);
// Here endingindex is -1 i.e
c = A.slice(0, -1);
 
console.log(b);
console.log(c);

Output:
