Benchmark: module level regex vs scoped

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:

inside loop
const strNum= '34GB'; function run(strNum){ const results= strNum.match(/^([\d_]+(?:\.[\d_]+)?)\s*([KMGT])?(i)?([Bb])?$/); } for(let i=0; i<10000; ++i){ run(strNum); }
module level
const strNum= '34GB'; const regex= /^([\d_]+(?:\.[\d_]+)?)\s*([KMGT])?(i)?([Bb])?$/; function run(strNum){ const results= strNum.match(regex); } for(let i=0; i<10000; ++i){ run(strNum); }
