I'm using the following code to select all hrefs from a web page:

const hrefs = await page.$$eval('a', as => as.map(a => a.href));

I need to know how to filter those hrefs with the ones that only contains /product/ & contains /c/ for example?

You can add Array.prototype.filter() with String.prototype.includes() predicates:

const hrefs = await page.$$eval(
 'a',
 as => as.map(a => a.href)
 .filter(href => href.includes('/product/') && href.includes('/c/'))
);

You can achieve this by using .filter instead of .map method.

Here is what you can try:

const hrefs = await page.$$eval('a', as => as.filter((d)=>
 return (d.contains('/c/') && d.contains('/product/'))
 ));
