How to convert camelCase to Sentence case in JavaScript

In this tutorial, we are going to learn about how to convert a from camelCase string to Sentence case in JavaScript.

Consider we have a camelCase string myName and we need to convert it to Sentence case string My Name.

myName --> My Name
howAreYou --> How Are You


  1. First, we need to add a space between strings using the replace method.
  2. Now, we need to access the first character from a string and convert it to upper case and join it to the final string by slicing the first character.
const str = "myName";

 // adding space between strings
const result = str.replace(/([A-Z])/g,' $1');

// converting first character to uppercase and join it to the final string
const final = result.charAt(0).toUpperCase()+result.slice(1);

console.log(final); // "My Name"
