JavaScript Window atob() method

The atob() method in JavaScript is used to decode a base-64 encoded string. This method takes a single argument, which is the base-64 encoded string that you want to decode, and returns the decoded string.

Here is an example of how the atob() method works:

const encodedString = 'SGVsbG8sIHdvcmxkIQ==';

const result = atob(encodedString);

// the result will be: 'Hello, world!'

In the code example above, we first declare a string called encodedString that contains a base-64 encoded string. We then use the atob() method to decode the encodedString string. We pass the encodedString string as an argument to the atob() method to specify the base-64 encoded string that we want to decode.

As a result of calling the atob() method, the result variable will be set to 'Hello, world!', which is the decoded value of the encodedString string. The atob() method decodes the base-64 encoded string and returns the original, unencoded string.
