Better ways to modify string with multiple methods using JavaScript

To modify string, you can use toLowerCase() as well as toUpperCase(). Let’s say the following is our string −

var sentence = "tHIS iS tHE JavaScript pROGRAM";

To modify and display in proper case, the code is as follows −

Example

var sentence = "tHIS iS tHE JavaScript pROGRAM";
function modifyStringWithMultipleMethods(sentence) {
   return sentence.charAt(0).toUpperCase() +
   sentence.slice(1).toLowerCase();
}
console.log(modifyStringWithMultipleMethods(sentence));

To run the above program, you need to use the following command −

node fileName.js.

Here, my file name is demo51.js.

Output

This will produce the following output −

PS C:\Users\Amit\JavaScript-code> node demo51.js
