Javascript is one of the most popular programming languages in the world. There are so many advantages of Javascript, which is why it is a common choice among many programmers. If you are a programmer or you’ve just started programming, you must have heard about a lot of programming languages, including Javascript.
JavaScript is a widely used programming language. It is known for how easy it is to use and its flexibility. Javascript plays a very important role in modern web development since it improves the user experience and has transformed the way developers and programmers interact with websites and web applications. Javascript is used to build web applications, mobile applications, desktop applications and many others.
If, as a programmer, you’re looking for a programming language that is very fast, very easy to learn, and also popular among programmers, then JavaScript is a great option. In this article, we’ll be learning a lot about JavaScript and its advantages.
What Is Javascript?
Before looking at some of the advantages of Javascript, let’s have a good understanding of what Javascript is and its uses.
JavaScript is one of the most popular and easy programming languages among programmers that creates an interactive web experience. Javascript is used to make a lot of web pages user-friendly and very adaptive. It is used by developers and programmers to produce animations, games, and other interactive features.
The founder of JavaScript is Brendan Eich, a well-known programmer and developer. Brendan Eich developed Javascript in 1995, and the programming language was developed in just 10 days while Brendan Eich was still working at the Netscape Communications Corporation.
Javascript was initially developed to make HTML pages, which are static and less interesting, more interactive. Over the years, the JavaScript programming language has transformed and evolved into a very important and foundational tool for web development.
Javascript is a popular choice among programmers and developers because it helps to create responsive web pages and is also used to improve the user interface experience, unlike other well-known programming languages that are basically used for server-side scripting or desktop applications. Not only that, Javascript is a great option among developers and programmers because it helps them add features such as animations, user interactions, and real-time updates, without reloading the entire web page.
Advantages of JavaScript
We’ve got a good knowledge of Javascript. Let’s look at some of the advantages of Javascript that have made it one of the most popular and convenient programming languages among developers and programmers.
1. It has a very simple Syntax
One of the advantages of JavaScript is that it has a very simple syntax. This means that the Javascript programming language is very easy to use and understandable. The Javascript programming language is a great option for beginners since it has a very simple syntax that can be easily understood by beginners as well as experienced programmers. Hence, Javascript is a very beginner-friendly programming language and a great choice among many.
2. Client-side Execution
One of the advantages of Javascript is the client-side execution feature. This means that when the JavaScript code is launched, it is executed in the browser of the client. This is what the JavaScript “client-side” execution means. The client that is being referred to is the user who is using the browser to access different web pages.
This indicates that when a user loads a web page in their browser, the Javascript of that particular web page gets executed there on the user’s browser and the user doesn’t have to deal with any software that’s not needed. Hence, client-side code execution makes JavaScript a more convenient and flexible programming language.
3. Huge Community Support
As we discussed earlier, Javascript was developed by Brendan Eich in 1995. Since its creation, JavaScript has been widely accepted all over the world and it has a large community of developers. The developer community supports you as a new programmer or developer using the Javascript programming language to solve errors or difficulties you may encounter when using Javascript as you develop an application.
4. Validation on Browser
One of the advantages of Javascript is the validation of browser features. One amazing feature of JavaScript is that it gives programmers and developers access to perform validation for email addresses and ensure the consistent use of valid data.
When filling out online forms, notifications or validation errors like email is not valid or incorrect format come up. This is possible with the validation of browser features in Javascript. The validation can only be seen and is done on the client’s side before being sent to the server. If wrong data is not being validated on the client’s side and is being sent to the server, it would get validated there, and this would affect the bandwidth and take more time than it is required to. Hence, having validation on the client side gives protection to the bandwidth from being affected and it also saves time.
5. Fast-paced Growth and Dynamic Development
The fast-paced growth and dynamic development of JavaScript are two of its outstanding advantages. Since it was developed in 1995, Javascript has been constantly evolving.
The Javascript programming language is dynamic, which means that it is developed, updated, and maintained to meet the requirements of the ever-evolving modern world.
6. Amazing Libraries/Frameworks
Javascript programming language is known to have outstanding libraries or frameworks. This is one of the advantages of JavaScript. Javascript is known for its exceptional frameworks, some of which have become popular, like Vue.js, and Angular.js, a library such as React.js, and runtime environments such as Node.js. These frameworks are used in different application development projects based on their requirements. React.js is the most popular JavaScript library that is widely used in front-end website development by programmers and developers.
It would also interest you to know that most of the popular and widely used frameworks or libraries are Javascript-based.
Advantage of JavaScript: Why is it so Important?
We’ve looked at what Javascript is and some of the advantages of Javascript. Outside of the many advantages of Javascript, why is the programming language so important? Let’s find out.
1. Javascript has very Powerful Functions
Javascript functions are one of the most important factors that make JavaScript a very powerful programming language and a great option in the world of programming. The functions available in Javascript have helped programmers a lot in functional programming. Javascript is a very important programming language among programmers and developers because of its powerful functions. These powerful functions give developers access to perform very complex tasks.
It has different powerful function features available, including giving programmers access to create and manipulate objects. The objects created can be changed and updated as time goes on. This means that objects on JavaScript are mutable
2. Multi-functional Website Development
JavaScript’s multi-functional ability makes it one of the best programming languages for developing dynamic and interactive websites. Javascript programming language is used for both front-end development, back-end development, and the development of mobile apps.
4. Client-side Scripting
Why is JavaScript so important? Just as it was discussed earlier, JavaScript has a client-side execution feature. This means that when the JavaScript code is launched, it is executed in the browser of the client, so users do not necessarily have to download any extra files to write and execute JavaScript code, because this can be executed in the browser too.
Advantage of JavaScript: Apps that are Powered Using JavaScript
The JavaScript programming language is very flexible and it is used in a lot of domains. This has led to the invention and creation of a lot of popular applications. Some of the applications that are being powered using JavaScript are listed below.
- Social media applications like LinkedIn, X, Facebook, and Instagram make use of the JavaScript programming language for their ever-changing interfaces and real-time updates.
- Single-page applications (SPAs) like Gmail, Google Maps, and GitHub all make use of JavaScript frameworks like Angular, React, or Vue.js to come up with a convenient and very responsive user experience without having to constantly reload web pages.
- The third on the list of apps powered by Javascript are streaming apps. Streaming apps like Netflix, Spotify, and YouTube all make use of JavaScript to provide a seamless and very interactive media streaming experience to all the users using any of the streaming apps.
- The availability of shopping websites like Amazon and eBay has made the lives of many easier. These shopping websites are powered by JavaScript, which gives users of these applications a dynamic, user-friendly shopping experience. Due to the function of Javascript, these shopping websites now have features like product recommendations, reviews, and live updates.
