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:  Photo by [Erik Lucatero](https://unsplash.com/photos/FfL2yW0Rwes?utm_source=unsplash&utm_medium=referral&utm_content=creditCopyText) on [Unsplash](https://unsplash.com/?utm_source=unsplash&utm_medium=referral&utm_content=creditCopyText) ### 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 }) **Already knew them all?** You’re a true hipster hacker, you can read more [tips & tricks for writing better code](https://medium.com/@ketacode/the-non-secret-formula-for-writing-better-code-e41d1ff38682).
