— As long as they have a pure interface


const map = (list, fn) => {
const result = [];
for (const item of list) {
return result;

— This is clearly imperative

— But the function itself is pure

— When called

— Since:
* There is no state between calls
* It will always return the same output for the same input

— I bet, it will eat a lot of "functional style" because it's simplier

— Guys, am i right when i say its obsolete to write an await in this situation:
await api.patch.then(res => res)

— The then is the alternative to the await, isnt it?

— It's the opposite

— await api.patch.then(res => res)
const res = await api.patch
