Binary to ascii mapping in JavaScript

Question

This morning I've seen this on Twitter: http://mynewtechworld.tumblr.com/post/135545896048

I case that somebody can't see the image:

I
01101100
01101111
01110110
01100101
you.

Just for fun I wrote this binary to ascii-converter in JavaScript:

var chars = [
 'I ',
 0b01101100,
 0b01101111,
 0b01110110,
 0b01100101,
 ' you.'
];
var result = chars.reduce(function(previous, current) {
 if (!isNaN(current)) {
 current = String.fromCharCode(current.toString());
 }
 return previous + current;
}, '');

My complete implementation on CodePen

• Caridorc: Welcome to CodeReview, a fine first question :)

Answer 1

I suggest splitting:

• Converting binary to ascii
• Concatenating

After defining binaryToNumber and add. the final code will look much simpler:

var result = chars.map(binaryToNumber).reduce(add)
