JavaScript fundamentals

JavaScript is a programming language used to add custom behavior to your web page by executing code in your web browser side (commonly named client side). So, this allows us to create rich dynamic projects such as games, execute custom code in response to events when the user presses some button, apply dynamic effects to our web page elements, form data validation, and so on.

JavaScript as a single language is very flexible, and there is a big community of developers writing and unlocking additional functionality, big companies working on new libraries and of course, we as empowered developers ready to get all these features and make the web awesome.

There are a few basic characteristics of JavaScript:

• Dynamic typing
• Object oriented
• Functional
• Prototyped
• Event handling
