Highlights and Challenges of JavaScript

JavaScript is a lightweight, interpreted, or just-in-time compiled programming language with first-class functions. While it is most well-known as the scripting language for Web pages, many non-browser environments also use it, such as Node.js, Apache CouchDB and Adobe Acrobat. JavaScript is a prototype-based, multi-paradigm, single-threaded, dynamic language, supporting object-oriented, imperative, and declarative styles.

Like with all programming languages, JavaScript has certain advantages and disadvantages to consider. Many of these are related to the way JavaScript is often executed directly in a client’s browser. But there are other ways to use JavaScript now that allow it to have the same benefits of server-side languages.

Highlights

1. JavaScript is easy to understand and learn. JavaScript’s syntax was inspired by Java’s and is relatively easy to learn compared to other popular languages like C++. It is also very feasible to implement, saving developers a lot of money for developing dynamic content for the web.
2. Since all modern browsers support JavaScript, it is seen almost everywhere on the web, and with the advent of Node.js, is increasingly used on the backend. There are countless resources to learn JavaScript. Both StackOverflow and GitHub show an increasing amount of projects that use JavaScript, and the traction it’s gained in recent years is only expected to increase.
3. JavaScript works perfect with other programming languages and therefore numerous developers prefer it in developing many applications. Any webpage or the script of another programming language can contain it.
4. Data validation can be done within the browser itself rather than being forwarded to the server because JavaScript is client-side. In case of any discrepancy, the whole website needs not to be reloaded. The browser updates only the selected segment of the page.
5. JavaScript provides various interfaces to developers for creating catchy webpages. Drag and drop components or sliders may give a rich interface to the webpages. This leads to improved user-interactivity on the webpage.
6. Popular frameworks such as Vue.js, and Angular.js, a library such as React.js, and runtime environments such as Node.js, all of these are JS based only with different use cases and are used in the application development based on the requirements. The point here is that with the increasing demand for technology, various kinds of JavaScript frameworks and libraries have proved to be very helpful for the developer community. Adding to that, Nowadays, React.js is one of the most popular JavaScript libraries which is aggressively used in Front-end Website development.

Challenges

1. Since JavaScript code is executed on the client-side, bugs and oversights can sometimes be exploited for malicious purposes. Because of this, some people choose to disable JavaScript entirely.
2. While server-side scripts always produce the same output, different browsers sometimes interpret JavaScript code differently. These days the differences are minimal, and you shouldn’t have to worry about it as long as you test your script in all major browsers.
3. Unlike C++, JS does not support Multiple Inheritance. In other words, JavaScript only supports single inheritance and not multiple inheritance. Some programs may require this object-oriented language characteristic.

After weighing the pros and cons of JavaScript we can envision the full picture of this field. While JavaScript is a field with many lucrative advantages, it also suffers from its disadvantages.
