How to Generate a Random Boolean Value in JavaScript

To generate a random boolean value in JavaScript, follow these steps:

  1. Open the Terminal/SSH and type node to start practicing coding.
  2. Use the Math.random() method to generate a random number.
  3. Check if the random number is greater than or equal to 0.5.
  4. Return true if the number is greater than or equal to 0.5, otherwise return false.

Here's a concise implementation of the code:

const randomBoolean = () => Math.random() >= 0.5;

You can test the function by calling randomBoolean() which will return either true or false.
