How to decode a binary string in JavaScript

Decoding a binary string in JavaScript is not a straightforward task because there is no general method for it.

But don’t fret. We can code our own solution for this problem.

Here’s to show how to decode a binary string in JavaScript with simple steps.

Decode a binary string

Below are simple steps to follow to decode a binary string in JavaScript:

• Step 1: Split the binary into an array of strings using the .split() method.

• Step 2: Iterate over the elements of the new array created to change each element to a decimal. We can do this by using the .map() method.

Note: We change the elements to decimal to make it easier to convert them to text later. This is because whole numbers can’t be changed to text in JavaScript.

• Step 3: Use String.fromCharCode with .map() to change each element of the array to text.

• Step 4: Add the new array elements together to create a string. This can be done with the .join() method.

• Step 5: Return the new string.

Below is an example:
