You're probably here because you don't know everything.

Thinking you know what you think you know is the problem,

promises

i promise i'll get back to you as soon as i know

const myFirstPromise = new Promise((resolve, reject) => {
  // do something asynchronous which eventually calls either:
  //
  //   resolve(someValue); // fulfilled
  // or
  //   reject("failure reason"); // rejected
});

async/await

make this asynchronous and then ahh, wait here until i get back to you

also, it's just a more readable promise

function resolveAfter2Seconds() {
  return new Promise(resolve => {
    setTimeout(() => {
      resolve('resolved');
    }, 2000);
  });
}

async function asyncCall() {
  console.log('calling');
  var result = await resolveAfter2Seconds();
  console.log(result);
  // expected output: 'resolved'
}

currying

i see you have many parameters, why don't you curry them in separate buckets

function volume(l,w,h) {
  return l * w * h;
}
const aCylinder = volume(100,20,90) // 180000l

function volume(l) {
  return (w) => {
    return (h) => {
      return l * w * h
    }
  }
}
const aCylinder = volume(100)(20)(90) // 180000

curry

immutability

an object whose state can not be modified after it is created

const obj = {
  prop: 42
};

Object.freeze(obj);

obj.prop = 33;
// Throws an error in strict mode

console.log(obj.prop);
// expected output: 42

const confusion

this

this is hard

i can't do this

globalThis

is exactly what it says it is: the globalThis

Serverless, Async/Await, Immutability and Other Things You Pretend to Understand

By Tara Z. Manicsic

Serverless, Async/Await, Immutability and Other Things You Pretend to Understand

Join me as we walk through plain English descriptions and joyful anecdotes of these mysterious terms. I aim to help you understand these terms enough to explain them to all the people you know that also pretend to understand them. “Currying? Sounds delicious!” is something you can avoid saying after this session.
