What would be a nice elegant functional solution for anding two boolean arrays in ES6?

const a1 = [true, false, false]
const a2 = [true, true, false]

应导致:

[true, false, false]

推荐答案

使用可以使用

Use can use Array#map to iterate the 1st array, and get the value of the 2nd array using the index (the 2nd param in the callback):

const a1 = [true, false, false]
const a2 = [true, true, false]

const result = a1.map((b, i) => b && a2[i]);

console.log(result);
