Benchmark: Native JS: concatenate string with + vs template literals vs String.concat - My test

Script Preparation code:

var name = "name";
var id = "id";

Tests:

using plus operator
for (let i = 0; i < 10000000; ++i) { let result = id + ": 1, " + name + ": someItem"; }
using concat function
for (let i = 0; i < 10000000; ++i) { let result = "".concat(id, ": 1, ", name, ": someItem"); }
using template literals
for (let i = 0; i < 10000000; ++i) { let result = `${id}: 1, ${name}: someItem`; }
