Following the original [JavaScript hacks for hipsters](https://hackernoon.com/javascript-hacks-for-hipsters-624d50c76e8e), here’s some new goodies. Coding JavaScript in 2018 is actually fun again!

Here’s a photo of non-JavaScripter, non-hacker, non-ES6er, non-hipster on a PacMan background:

### Hipster Hack #1 — Swap variables

Using `Array Destructuring` to swap values

let a = 'world', b = 'hello'  
\[a, b\] = \[b, a\]  
console.log(a) // -> hello  
console.log(b) // -> world

// Yes, it's magic

### Hipster Hack #2 — Async/Await with Destructuring

Once again, `Array Destructuring` is great. Combined with `async/await` and promises to make a complex flow — simple.

const \[user, account\] = await Promise.all(\[  
  fetch('/user'),  
  fetch('/account')  
\])

### Hipster Hack #3 — Debugging

For anyone who likes to debug using `console.log`s, here’s something awesome (and yes, I heard of `console.table`):

const a = 5, b = 6, c = 7  
console.log({ a, b, c })

// outputs this nice object:  
// {  
//    a: 5,  
//    b: 6,  
//    c: 7  
// }

### Hipster Hack #4 — One liners

Syntax can be so much more compact for array operations

// Find max value  
const max = (arr) => Math.max(...arr);  
max(\[123, 321, 32\]) // outputs: 321

// Sum array  
const sum = (arr) => arr.reduce((a, b) => (a + b), 0)  
sum(\[1, 2, 3, 4\]) // output: 10

### Hipster Hack #5 — Array concatenation

The spread operator can be used instead of `concat`:

const one = \['a', 'b', 'c'\]  
const two = \['d', 'e', 'f'\]  
const three = \['g', 'h', 'i'\]

// Old way #1  
const result = one.concat(two, three)

// Old way #2  
const result = \[\].concat(one, two, three)

// New  
const result = \[...one, ...two, ...three\]

### Hipster Hack #6 — Cloning

Clone arrays and objects with ease:

const obj = { ...oldObj }  
const arr = \[ ...oldArr \]

Update: As mentioned in the comments — this is a shallow clone.

### Hipster Hack #7 — Named parameters

Making function and function calls more readable with destructuring:

const getStuffNotBad = (id, force, verbose) => {  
  ...do stuff  
}  
const getStuffAwesome = ({ id, name, force, verbose }) => {  
  ...do stuff  
}

// Somewhere else in the codebase... WTF is true, true?  
getStuffNotBad(150, true, true)

// Somewhere else in the codebase... I ❤ JS!!!  
getStuffAwesome({ id: 150, force: true, verbose: true })
