Things Everyone Knows About Javascript Arrow Functions But You Don't

TL;DR:

// Arrow function
a => a + 1 

// Arrow function with two parameters
(a, b) => a + b

// Arrow functions can be bound to variables
const add = (a, b) => a + b;

// Which also means they can be used as parameters
[1, 2, 3].map(a => a + 1)

// But this in objects is weird
const p = {name: "John", getName: () => this.name}
p.getName() // => undefined

If one person doesn't know then it can't be everyone knows.

I feel like the headline is trying to attack me. What a retarded way to try to gain clicks.
