babel-101

Learning ES6 and Babel via tower-of-babel.

random notes taken

My first impression to Template String is meh. But it comes pretty handy for printing a string that contains many variables in it.
extends and super reminds me of Java somehow...
A module can export const and function.
ES6: export, CommonJS: exports
ES6: import {} from <PATH>, CommonJS: require()
export default so importing doesn't require {}.
let and const are simple but pretty useful I think.
Computed property is kinda cool. Not sure if I will be using it that much though.
I don't think I understand Iteratable really well. for..of is OK.
Generator: feeling much better than Iteratable! At least generators don't require confusing boilerplate code.
function*(){}() <- there are parentheses after function declaration to make it work. Generators are objects, not functions.
I got more understandings from this video tutorial about Generators at Egghead.io.
Destructure: from the tutorial, I quite understand what destructure is. but the exercise re-confused me. To me, destructure is useful for swapping variables.
Destructure chapter should be before Iteratables and Generators. Seeing a destructure usage in chapter 8 also confused me.
Arrow functions - can be super short yet not that easy to understand. (or i just need more time with them actually)
For the first time I use Array.prototype.reduce() actually.
Spread call is kinda cool too. Combining with Array.prototype.reduce() can simplify the function quite well.
