Most of the time, I wrote "clever" code.
At best, a one-liner.
Easy to create with some functional JavaScript.
const f = (o) => o.reduce((a, { b, c }) => [...a, ...(c ? [b * 3] : [])], []); console.log( f([ { b: '1', c: true }, { b: '2', c: false }, { b: '3', c: true }, { b: '4', c: true }, ]), ); Today I found this code in my archives.
I gave it to a friend and he was like ":-(".
He has some basic JS knowledge and said,
that he can't understand it.
I re-wrote my code to this:
// array for all option objects const options = [ { value: '1', assigned: true }, { value: '2', assigned: false }, { value: '3', assigned: true }, { value: '4', assigned: true }, ]; const filter = options // only use option objects that have a truthy assigned value .filter((option) => option.assigned) // take the option value and multiply it with 3 .map((option) => option.value * 3); console.log(filter); To close this learning, I've found something in my notes:
Never ever write "clever" code to increase your ego. Write simple code, so that you and all readers do understand it.
