Benchmark: flat() vs reduce.concat() vs es-toolkit flatten()

Tests:

reduce.concat()
const params = [[ 1, 2], ["hello", true, 7]]; const other = params.reduce((acc, val) => acc.concat(val));
flat()
const params = [[1, 2], ["hello", true, 7]]; const other = params.flat();
es-toolkit flatten()
function flatten(arr, depth = 1) { const result = []; const flooredDepth = Math.floor(depth); const recursive = (arr, currentDepth) => { for (let i = 0; i < arr.length; i++) { const item = arr[i]; if (Array.isArray(item) && currentDepth < flooredDepth) { recursive(item, currentDepth + 1); } else { result.push(item); } } }; recursive(arr, 0); return result; } const params = [[ 1, 2], ["hello", true, 7]]; const other = flatten(params);
