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/'))
          );
