Benchmark: string cast vs template literal cast vs cached empty string cast with random values

HTML Preparation code:

<!--your preparation HTML code goes here-->

Script Preparation code:

/*your preparation JavaScript code goes here
To execute async code during the script preparation, wrap it as function globalMeasureThatScriptPrepareFunction, example:*/
async function globalMeasureThatScriptPrepareFunction() {
    // This function is optional, feel free to remove it.
    // await someThing();
}

const TEST_ITERATIONS=100000;
const emptyString = '';

Tests:

String literal
/*When writing async/deferred tests, use `deferred.resolve()` to mark test as done*/ for (let i=0; i++; i<TEST_ITERATIONS) { const stringLiteral = String(Math.random() + i); }
Template literal
for (let i=0; i++; i<TEST_ITERATIONS) { const templateLiteral = `${Math.random() + i}` }
Cast
for (let i=0; i++; i<TEST_ITERATIONS) { const cast = '' + (Math.random() + i); }
Cast cached string
for (let i=0; i++; i<TEST_ITERATIONS) { const castCached = emptyString + (Math.random() + i); }
