In this article, you'll learn how to Base64 decode any Base64 encoded data back to binary data using Node.js built-in Buffer API.

In this article, you'll learn how to Base64 Encode a String in Node.js. The simplest way to convert a string to Base64 encoded format in Node.js is via the built-in Buffer class.

Learn how to convert a given character to ASCII code and how to convert an ASCII code to its associated character in Javascript.

Learn how to decode a Base64 encoded string using Javascript. Base64 Decoding to UTF-8 strings is very simple and can be done with the built-in atob() function. However, for decoding to any 16-bit-encoded string, you need to convert the UTF-8 array of characters to 16-bit-encoded DOMStrings.

In this article, you'll learn how to encode a string to Base64 encoded format. Javascript has a built-in function named btoa() that you can use to perform Base64 encoding. However, the btoa() function doesn't recognize DOMStrings which are 16-bit encoded. To encode DOMStrings, you need to convert the UTF-16 DOMStrings to UTF-8 array of characters.

Javascript Url Decoding example. Learn how to decode URI components in Javascript. You can decode URI components in Javascript using the decodeURIComponent() function. It performs the inverse operation of encodeURIComponent(). It uses UTF-8 encoding scheme to decode URI components.
