It may be used immediately in the browser and is both quick and light (client machine).
People have been using it for a very long time, and it still works well.
It’s compatible with a wide range of other programming languages and software.
Decreases server burden because it is client-side.
Creates vibrant, dynamic, and rich pages.
It includes a lot of free utilities to improve functionality.
Using Node.js, JS functionality can be extended to the backend.
To write a JS code, you can use a code editor, an IDE, or even a notepad or Textpad. In contrast to programming using editors like notepad, where you must type everything from scratch, IDEs and editors offer a natural programming experience and results that come faster.
Let’s walk you through some JS fundamentals that you need to keep in mind before you start learning.
Although functions are units of behavior, in this context it’s crucial to note their independence. In other languages like Java or C#, you need to make function declarations inside of classes.
Indeed, objects are nothing more than a set of attributes. They are referred to as maps, hash maps, or hash tables in other languages. They’re dynamic, which means that properties can be added, changed, or removed after they’ve been formed.
In it, objects derive from predecessors known as prototypes. As was mentioned earlier, objects in this language are collections of properties. An object contains a “hidden” property that stores a reference to another object when it’s created. Prototype refers to the object being addressed.
Functions can define additional functions inside of them. Variables from the external functions may be referred to in the internal function. Additionally, when the outer function has finished running, the inner function can make references to variables from the outside function.
Don’t forget that JS is a single-thread language. This indicates that just one statement is performed at a time. The main thread doesn’t allow for simultaneous execution of two functions.
And now you’re all set. These were the main basics you should know before you start writing JS.
