Benchmark Run Result for: recursive string literal vs addition assignment

Test name	Executions per second
recursive string literal	5026.1 Ops/sec
addition assignment	6815.4 Ops/sec

Script Preparation code:

var values = [];
for (let i = 0; i < 1000; ++i) {
  values.push(i);
}

Tests:

recursive string literal
var f = i => `x = ${values[i]} or ${i < values.length ? f(i+1) : '0=1'}`; var result1 = f(0); console.log(result1);
addition assignment
var s = '0=1'; for (var i = 0; i < values.length; ++i) { s += `x = ${values[i]}`; } var result2 = s; console.log(result2);
