Javascript Foundation Course
The Javascript scripting language is widely used in the producing of modern full stack web applications. The language can be used for both the backend using frameworks such as NodeJS and then the front end using frameworks such as React. This course guides non-experienced programmers through the tasks of writing and maintaining applications written in Javascript.
