How to convert text to binary code in JavaScript?

Question

Text to Binary Code

I want JavaScript to translate text in a textarea into binary code.

For example, if a user types in "TEST

Answer 1

Try this:

String.prototype.toBinaryString = function(spaces = 0) {
    return this.split("").map(function(character) {
        return character.charCodeAt(0).toString(2);
    }).join(" ".repeat(spaces));
}

And use it like this:

"test string".toBinaryString(1); // with spaces
"test string".toBinaryString(); // without spaces
"test string".toBinaryString(2); // with 2 spaces
