Does the page timeout interrupt loop execution inside page context ? Puppeteer

Question

Considering the following example :

page.setDefaultTimeout(2000); // set a default timeout of 2s on the page

await page.$eval('selector', (el) => {
    while (true) {
        // do some stuff
    }
});

What will happen ? Does the loop blocks the execution forever or is it interrupted by the timeout ?

Answer 1

From the following test the answer is NO the page timeout will not interrupt an endless loop in pageFunction.

 page.setDefaultTimeout(1000);
 await page.exposeFunction('log', (val) => console.log(val));
 await page.goto('https://www.google.com/');
 await page.$eval('body', (el) => {
     let a=0;
     while (true) {
        log(a++);
     }
 });
