Does ES6 module importing execute the code inside the imported file?

Question

Does the code inside the js file gets run during the import? if yes, then once or each time? e.g.

// a.js
console.log(\"A\");
const a = \"a\"; 
export defaul         


        

Answer 1

In case someone is using TypeScript with "module": "es6" and wondering how to do this, use the globalThis keyword:

function outputMsg(msg: string) : void {
    console.log(msg);
}

// export function for global scope
globalThis.outputMsg = outputMsg;

and then call outputMsg("my console output") as usual in the Chrome DevTools console and it should autocomplete and run your function.

You could also rename your "global export":

globalThis.myCrazyFunc = outputMsg;

and call myCrazyFunc("crazy message") in the console.
