Consider this piece of code

// Initialise the variables to check when the code started
let total_time = performance.now();
let recursions = 0;
function test() {
    recursions++;
    if (recursions === 60) {
        // Check how long it took to do 60 recursions
        console.log(`${performance.now() - total_time}ms`);
    }
// Timeout to call it 17ms later
setTimeout(() => test(), 17);
}
test();

This is meant to show when 60 recursions have happened to ensure that certain parts of my code are fired off correctly (without needing setTimeout as it's blocking) and I get between 1200 - 1600ms for no reason. I used a modified version that measured how long it took and it gave 0ms (for no reason). Anyone know why? And will the same happen in node.js?

Code used to measure how long it took to do one recursion

let start_time = performance.now();
let total_time = performance.now();
let measure = 0;
function test() {
    start_time = performance.now();
    measure++;
    if (measure === 60) {
        console.log(`${performance.now() - total_time}ms`);
    }
    console.log(`Taken ${performance.now() - start_time}`);
}
test();
