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

var PADDING = "00000000"

var string = "TEST"
var resultArray = []

for (var i = 0; i < string.length; i++) {
  var compact = string.charCodeAt(i).toString(2)
  var padded  = compact.substring(0, PADDING.length - compact.length) + compact

  resultArray.push(padded)
}

console.log(resultArray.join(" "))
