Benchmark: concat, vs spread, vs push

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();
}

Tests:

concat
/*When writing async/deferred tests, use `deferred.resolve()` to mark test as done*/ a = [1,2,3]; a = a.concat([4,5,6]);
spread
a = [1,2,3]; a = [...a, ...[4,5,6]];
push
a = [1,2,3]; a.push.apply([4,5,6]);
