A client-side language
Java Script is a client-side language, which means that the code is executed directly in the user’s browser, rather than on a server. This allows for faster and more responsive web pages, as the browser can process the Java Script code without having to communicate with a server.
A wide range of built-in functions and objects
Java Script also has a wide range of built-in functions and objects that can be used to perform various tasks. For example, the Math object has properties and methods for performing mathematical operations, while the Date object can be used to work with dates and times.
Java Script is also an object-oriented language
Java Script is also an object-oriented language, which means that it has a way to organize the code in the form of objects. An object is a collection of properties and methods that are used to represent a specific item or concept.
Java Script is a powerful and versatile language
Overall, Java Script is a powerful and versatile language that is essential for creating dynamic and interactive websites. While it may have a bit of a learning curve. The effort is well worth it as it opens up a whole new world of possibilities for web development.
In addition to the basic concepts mentioned above. Java Script also includes more advanced features such as closures, prototypes, and scope.
Closures are a way to create functions that remember the variables and state of the surrounding code, even after the function has finished executing. This allows for powerful and flexible programming patterns, such as creating private variables and methods within an object.
Prototypes are a way to create object inheritance in Java Script. Every object has a prototype, which is another object from which it inherits properties and methods. This allows for code reuse and efficient inheritance of common functionality.
Scope refers to the accessibility of variables and functions within different parts of the code. Java Script has both global and local scope. With variables and functions defined in the global scope being accessible from anywhere. And those defined in a function scope only being accessible within that function.
Arrow functions are a shorter
Arrow functions are a shorter and more concise way to write functions, they are anonymous and can’t be used as constructors.

Template literals allows you to embed expressions inside string literals using back ticks which is more readable and easy to use.
The spread operator allows you to spread elements of an iterable object such as an array into a new array. Or to spread the properties of an object into a new object.
How to learn Java Script
To learn Java Script, you can start by experimenting with small scripts and gradually build your knowledge and skills over time. There are also many resources available online, such as tutorials. Documentation, and forums, where you can learn from other developers and get help with any questions you may have.
