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) // 180000curry
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: 42const confusion
this
this is hard
i can't do this
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.
