php intermediate programmer, how much js knowledge do you need? Can you summarize it?
what PHP programmers do is basically Internet development, inseparable from dealing with the front end. How much you need to know has something to do with what your company asks you to do. Basically, big companies require you to be specialized and be proficient in PHP. A small company may require you to know more about everything.
as long as you are proficient in PHP, it doesn't matter if you don't know anything about js. However, there is still something to know about HTTP, such as what are the differences and characteristics before HTTP1.0 1.1.2.0, what are the differences and meanings of, http code. How to configure cross-domain, these.
if you have to understand something, you don't need to write much to understand js, from the principle and framework, but as long as there are common front-end frameworks, such as vue, react angular, which face front-end separation, the back-end php only needs to pay attention to the provision of interfaces and does not need to provide page rendering.
if it is an ordinary website, you need to know some rendering knowledge of browsers. Then, in the way of php, the back end generates the page html, and spits it to the front end for rendering.
