In Javascript, you can call a function before it is defined and you won’t get an error ‘Uncaught ReferenceError’. The reason behind this is hoisting where the Javascript interpreter always moves the variables and function declaration to the top of the current scope before the code execution. Third-party libraries and frameworks can be used to accelerate the process of creating sites as well as applications. After studying HTML and CSS, you should learn JavaScript to create dynamic and interactive web pages for your users.
