Introduction

In this lab, we will explore how to convert a string into an array of characters in JavaScript. This is a common task in programming when dealing with strings, as it allows you to manipulate individual characters within the string. By using the spread operator, we can easily convert a string into an array of characters in just a few lines of code.

How to Convert a String to an Array of Characters in JavaScript

To convert a string to an array of characters in JavaScript, follow these steps:

  1. Open the Terminal/SSH and type node to start practicing coding.
  2. Use the spread operator (...) to convert the string into an array of characters.
  3. Define a function called toCharArray that takes a string as an argument and returns an array of its characters.
  4. Call the toCharArray function with the string you want to convert as the argument.
  5. The function will return an array of characters.

Here's the code:

const toCharArray = (s) => [...s];

toCharArray("hello"); // ['h', 'e', 'l', 'l', 'o']
