In this FullStackWebDevelopment tutorial series video, We learn how to link a #javascript file inside our HTML code.

Instead of defining the javascript inline it is a better practice to define it outside and link the file to the code. This can be done by providing the path to the js file inside the #script tag. This external javascript file is linked inside the head tag instead of the body.

The javascript program we wrote earlier was inline javascript which is generally not a good practice. It makes the code look complicated also it becomes difficult to debug. An external javascript file linked through the script keeps the code in an organised manner, making it easy to find bugs and debug it.

To define it outside and link the file code we perform refactoring. Refactoring is the process of changing a software system in such a way that it does not alter the external behavior of the code yet improves its internal structure.

JavaScript #comments :
// It is used for single line commenting. Any line of code that starts with // will not be executed or ignored by Javascript.
/*......*/ It is used for multiline commenting. All the lines of codes between them will not be executed or ignored.
