How do you convert to base 26?

With “Base 26”, you use the letters of the alphabet (not 0 to 9). Some people start with A=0, B=1, etc. But it seems more natural to use A=1, B=2, etc, as everyone thinks that A is the first letter, B is the second, and so on. It is fun to use Base 26, type your name in, and see what number you are!

How do you convert number between different base in JavaScript?

Answer: By using the parseInt() function, we can convert numbers between different bases in JavaScript. This function takes a string as the first parameter, and the base as a second parameter.

How to convert a string to a base64 encoding?

Base64 Encoding To convert a string into a Base64 encoded string, we need to first create a buffer from the given string by using the Buffer.from () method. This method takes two parameters, a plain-text string, and the character encoding, and creates a buffer or binary data array for the given encoding.

Which is the default encoding in Node.js?
