Clojure Destructuring Tutorial and Cheat Sheet

(Related blog post)

Simply put, destructuring in Clojure is a way extract values from a datastructure and bind them to symbols, without having to explicitly traverse the datstructure. It allows for elegant and concise Clojure code.

Vectors and Sequences

// Promise.all is good for executing many promises at once
Promise.all([
  promise1,
  promise2
]);

// Promise.resolve is good for wrapping synchronous code
Promise.resolve().then(function () {
  if (somethingIsNotRight()) {
    throw new Error("I will be rejected asynchronously!");

"Everything is an expression"... since ES1?

Many languages support "expression-only" semantics, allowing to use any construct in an expression position.

NOTE: the difference between expressions and statements is that the former produce a value, while the later don't.

For example, Ruby's if-expression:

x = 10

Rx.Observable
    .interval(500)
    .flatMap(() => [1, 2, 3] /* in angular you will call getData() to make an HTTP request */)
    .map(x => x + 1)
    .subscribe(x => console.log(x))

function getData() {
  return this.http
      .get('https://api.spotify.com/v1/search?q=' + term + '&type=artist')
      .map((response) => response.json())
