Benchmark: JS array spread vs concat vs avoiding

Tests:

JS spread
const arr1 = [ 1,2,3 ]; const arr2 = [ 4,5,6 ]; function sum(arr){ return arr.reduce((prev, curr) => prev + curr, 0); } sum([...arr1,...arr2]);
JS Concat
const arr1 = [ 1,2,3 ]; const arr2 = [ 4,5,6 ]; function sum(arr){ return arr.reduce((prev, curr) => prev + curr, 0); } sum(arr1.concat(arr2));
Avoiding
const arr1 = [ 1,2,3 ]; const arr2 = [ 4,5,6 ]; function sum(arr){ return arr.reduce((prev, curr) => prev + curr, 0); } sum(arr1) + sum(arr2);
