According to the 2018, Hackerrank developer survey, javascript is the number one skill that companies are looking for in the tech industry. After all, javascript is the language that runs in the browser. And almost every company does business through a web application.

javascript frameworks are also the biggest gap between what employers demand, and what candidates can provide. This is because javascript still isn't a part of the core curriculum at many universities. Rising software engineers don't have javascript skills unless they learn on their own.
