concat
const arr1 = Array.from({ length: 5000}).map((_, i) => i); const arr2 = Array.from({ length: 5000}).map((_, i) => i); const arr3 = Array.from({ length: 5000}).map((_, i) => i); const finallArr1 = arr1.concat(arr2).concat(arr3);
forEach
const arr1 = Array.from({ length: 5000}).map((_, i) => i); const arr2 = Array.from({ length: 5000}).map((_, i) => i); const arr3 = Array.from({ length: 5000}).map((_, i) => i); const finalArr2 = []; arr1.forEach((e) => finalArr2.push(e)); arr2.forEach((e) => finalArr2.push(e)); arr3.forEach((e) => finalArr2.push(e));
spread
const arr1 = Array.from({ length: 5000}).map((_, i) => i); const arr2 = Array.from({ length: 5000}).map((_, i) => i); const arr3 = Array.from({ length: 5000}).map((_, i) => i); const finalArr3 = [...arr1, ...arr2, ...arr3];
