Eloquent CoffeeScript

Marijn Haverbeke's Eloquent JS is an excellent book, here's my solutions to the exercises written in CoffeeScript.

Run the examples

npm install coffeescript -g
coffee 1-triangle.coffee

Why CoffeeScript?

The golden rule of CoffeeScript is: “It’s just JavaScript.”

As the ES6 train gained a lot of momentum coffee lost steam. However, the trends still show download growth over the past few years and there's still a lot of big projects using it.

Version 2 changed the compilation target from ES3 to ES2015 and aligned with new language features like ES2015 Modules, classes, template literals, async / await and destructuring. Now that both languages are close to feature parity, the only compelling reason to write CoffeeScript is the clean expressive syntax.

I wrote CoffeeScript every day for fours years and then ES6+ for the last two, I've just been reacquainted and it's still a pleasure to program in. Keep an open mind and give it a try, you may enjoy it.

Things I like about ☕️

• Clarity of the program shines through with less syntax and significant whitespace
• Everything is an expression, statements like for, if and switch produce a value
• Implicit return of last statement
• Aliases, operators & shorthands allow for more expressive code
