JavaScript is the sole of programming just like HTML and CSS, which are the way to make a website breathe on the SERP. These elements make the website interactive because of JavaScript. It compels users to open it and look for the products and services the website is offering. JavaScript is a programming language that is used all over the world by programmers to design applications and websites. JavaScript has the potential to rule the world of programming due to the constant advancements, updates, and versions that are the highlight of the news only programmers know.
JavaScript is supported by browsers without needing to install any plugins. If you want to use JavaScript to start working as a programmer, get enough information here in this post.
What is JavaScript
JavaScript is an object-oriented, cross-platform, general-purpose, open-source scripting language, which is quite popular among developers and programmers. It has a lot of frameworks and libraries that make programming even simpler. It has given liberty to create any project just the way you want. It is really an easy and handy language that is worth learning if you want to build a career.
It is a high-level language that can manage small as well as large projects. It has methods, classes, comments, operators, variables, and template literals. These are the most important part of JavaScript. It is frequently used as a dynamic programming language that permits rich web experiences for mobile phones, tablets, and PCs.
Features of JavaScript
1. Dynamic typing
JavaScript makes dynamic typing possible, which means the variables’ data type is defined at runtime. It makes it simpler for programmers as they are not required to define the data type of variables at the time of programming. To declare a variable, all you need to do is to use var (variable) or ‘let’ keyword before writing the name of the variable.
2. Lightweight
As it is designed to handle data in browsers, it is lightweight to run easily without any delay. It has libraries that make the code lighter. It is an amazing feature of JavaScript that compels programmers to use it simply.
3. OOP
It is an acronym for object-oriented programming. JavaScript has refined the OOP concept. Some features of OOP include encapsulation, object creation pattern, inheritance, and code reuse pattern. Not every programmer uses all of these, but it is available for those who want to use them.
4. Interpreted language
JavaScript code runs line by line for every project created. The interpreter of JavaScript is used to interpret scripts, which is an inbuilt web browser’s component. As the code runs line by line, all JavaScript errors show up line-wise.
5. Portable
JavaScript is known as a portable or independent platform. It signifies that once JavaScript code is written, it can run anywhere on any platform and browser at any time without making any changes in the code. You can use it without the fear of getting an error when running on any other system or browser.
6. Functional
JavaScript is also known as a functional programming language that has objects that are built with the help of constructor functions. Every function used in programming points to various object types.
7. Based on prototype
In this programming language, prototypes have a place. Just like building a class in Java (suppose) and then constructing objects for classes. But JavaScript is simpler as you just need to specify the prototype of an object that is used to create more objects.
Conclusion
I have pointed out the aspects for beginners so that they can have enough information to use JavaScript to practice. JavaScript is a vast language with all the features I highlighted above. Once you get familiar, it becomes easier to start working on it.
