Friends,

This post will describe converting text from one case to another using javascript. In general programming, we need to convert a text to the following cases -

• Lower Case
• Upper Case
• Title Case

We will see the conversion one by one below -

To convert a text into lowercase using Javascript

function toLowerCase(str) {
   return str.toLowerCase();
}

You can use this by calling -

alert toLowerCase("HELLO WORLD");

To convert a text into uppercase using Javascript

function toUpperCase(str) {
   return str.toUpperCase();
}

You can use this by calling -

alert toUpperCase("hello world");

To convert a text into Titlecase using Javascript

function toTitleCase(str) {
   return str.replace(/\w\S*/g, function (txt) { return txt.charAt(0).toUpperCase() + txt.substr(1).toLowerCase(); });
}

You can use this by calling -

alert toTitleCase("hello world");
