Expanding on the solution provided by basarat, it is worth noting that this functionality is already integrated into the console.
console.time('myTask');
// Code to be timed goes here
console.timeLog('myTask');
console.timeEnd('myTask');
If you're looking for a straightforward way to time your code execution, check out this implementation:
/**
* Basic timer
*/
export function timer() {
let startTime = new Date().getTime();
return {
/** <integer>s e.g 2s etc. */
get seconds() {
const seconds = Math.ceil((new Date().getTime() - startTime) / 1000) + 's';
return seconds;
},
/** Milliseconds e.g. 2000ms etc. */
get ms() {
const ms = (new Date().getTime() - startTime) + 'ms';
return ms;
}
}
}
Here's how you can use it:
const timing = timer();
// Perform some actions
console.log(timing.ms);
There are various other methods available, including the built-in console.time function that you may want to explore.
This particular timer is coded in typescript and includes type definitions.

If you're looking for a Stopwatch similar to .NET's, you might want to consider using the @tsdotnet/stopwatch package.
To add this package to your project, simply run: npm i @tsdotnet/stopwatch
Here is an example of how to use it in your code:
import Stopwatch from "@tsdotnet/stopwatch"
(async () => {
const stopwatch = Stopwatch.startNew();
// Simulate a delay of 1000 milliseconds
await new Promise(resolve => setTimeout(resolve, 1000));
console.log(stopwatch.elapsedMilliseconds);
})();
Keep in mind that your tsconfig.json should target at least es2015 because of the promises used in the example above. This requirement is not specific to the @tsdotnet/stopwatch package.
