Script Preparation code:
 
/*your preparation JavaScript code goes here
To execute async code during the script preparation, wrap it as function globalMeasureThatScriptPrepareFunction, example:*/
const a = [];
async function globalMeasureThatScriptPrepareFunction() {
    // This function is optional, feel free to remove it.
    // await someThing();
    for(let i = 0; i < 100000; i++) {
      a.push(Math.floor(Math.random() * 1000));
    }
}
Tests:

  • join

     
    a.join('');

  • for loop concatenation

     
    let b = '';
    for(let j = 0; j < a.length; j++) {
      b += a[j];
    }
