Benchmark: String concatenation v.s. ES6 template

Script Preparation code:

function concatenation(a, b, c) {
	return "a = " + a + ", b = " + b + ", c = " + c;
}

function template(a, b, c) {
 	return `a = ${a}, b = ${b}, c = ${c}`;
}

var arrayTemplate = ["a = ", null, ", b = ", null, ", c = ", null];
function arrayJoin(a, b, c) {
  	arrayTemplate[1] = a;
  	arrayTemplate[3] = b;
  	arrayTemplate[5] = c;
  	return arrayTemplate.join("");
}

Tests:

Concatenation
for (var i = 0; i < 100; i++) { window.a = concatenation(i, "random", "text"); }
ES6 template
for (var i = 0; i < 100; i++) { window.a = template(i, "random", "text"); }
Array join
for (var i = 0; i < 100; i++) { window.a = arrayJoin(i, "random", "text") }
