While Java can be used to create web applications, it is more often used in game development and desktop app creation.

Front End Developer

Each browser has its own JavaScript engine — Chrome, for example, uses V8, while Firefox uses SpiderMonkey. JavaScript’s front end benefits aren’t limited to improving web page design, however. Programmers can also use JavaScript-based development frameworks such as React.js and Angular to produce complex, interactive web applications. JavaScript variables also have different scopes depending on where you define them. The language uses functions — subprograms that are designed to perform a particular task in the overall program.

As we explained in our history section, JavaScript was designed with front end web development in mind. The language allows programmers to create dynamic pages and provide a responsive, engaging experience for website visitors. Developers who know JavaScript can also use libraries like Reveal.js, Swiper.js, Greensock.js and Anime.js, to enhance their images and animations. Like we mentioned earlier, when creating variable names, keep in mind that JavaScript is case-sensitive, so “year” and “Year” are two different variables. You can start your variable names with a letter or an underscore (_), but not a numeral.
