Some important and most usable operations on string.

In this articale we will know about Some important and most usable operations on string.

toUpperCase:

By this operation you can make your values to uppercase though you write your values in lowercase.

Example:

let name = “Nayemul Alam” ;
console.log(“My name is” + name.toUpperCase()); //output:_ My name is NAYEMUL ALAM //

toLowerCase:

This operation works the opposite of toUpperCase .

Example:

let name = “Nayemul Alam” ;
console.log(“My name is” + name.toLowerCase()); //output:_ My name is nayemul alam //

slice():

This slice() method extracts a section of a string and returns it as a new string, without modifying the original string.

Example:

let line = “My name is Nayemul Alam”;
console.log(line.slice(11, 23)); //output:_ Nayemul Alam //

trim():

The trim() method removes whitespace from both ends of a string.

Example:

let name = “ Nayemul Alam ” ;
console.log(“My name is” + name.toLowerCase()); //output:_ My name isNayemul Alam//
