Benchmark: Arrays Merge - MeasureThat.net

Tests:

Concat and Push - Map
var init=[10,11,12,13]; var params = [{val: [1,2]}, {val: [3,4]}, {val: [5,6]}, {val: [7,8]}]; init.push(...params.map(x=>x.val)); console.log(init);
Concat and Push - FlatMap
var init=[10,11,12,13]; var params = [{val: [1,2]}, {val: [3,4]}, {val: [5,6]}, {val: [7,8]}]; init.push(...(params.flatMap(x => x.val))); console.log(init);
Concat and Assign - FlatMap
var init=[10,11,12,13]; var params = [{val: [1,2]}, {val: [3,4]}, {val: [5,6]}, {val: [7,8]}]; init = init.concat(...params.flatMap(x=>x.val)); console.log(init);
