let arr = [1, 2];
arr.push(...[3, 4]);if you use the ES6, method, you should be able to push (.newarr)

a.concat (b) Array.prototype.push.apply (a, b) a.push (.b) what do you mean by this elegant standard
let arr = [1 hr class= 2 answer 3]
[] .push.apply (arr, [4je 5J 6])
the most elegant thing should be the direct extension operator ~:
const d = ['1','2'];
const x = ['3','4'];
const a = [...d, ...x];Previous: What little experience do you have in front and back end developers?

A solution that conforms to the meaning of the question function unique(arr) { const res = new Map(); return arr.filter((a) => !res.has(a) && res.set(a, 1)) } because map key is unique, you can change the an in res.has (a) to whate...
for example, duplicates according to the name attribute in the an array element. is this the simplest way? function unique(arr) { const res = new Map(); return arr.filter((a) => !res.has(a.name) && res.set(a.name, 1)) } reference...
this is what I do now. Is there a better way? let flag = true const listA = [1, 2, 3] const listB = [2, 3, 4] if (listA.length !== listB.length) { flag = false } else { listA.forEach(item => { if (listB.indexOf(it...
