What is JavaScript ?
JavaScript is a language that is translated, not compiled. The translation of the JavaScript code for the web browser is the responsibility of the JavaScript Translator, which is embedded in the browser.

What is JavaScript
Several websites use JavaScript (js), a lightweight object-oriented programming language, to script webpages. When applied to an HTML document, it is a fully interpreted programming language that enables dynamic interactivity on websites. It was made available in 1995 for using the Netscape Navigator browser to add programs to web pages. Since then, all of the other graphical web browsers have adopted it. Modern web applications that allow users to interact directly without reloading the page can be built using JavaScript. Js is used to provide a variety of interactivity and simplicity on the standard website.
However, there is no connection between JavaScript and the Java programming language. During a time when Java was gaining popularity in the market, the name was suggested and provided. Databases like CouchDB and MongoDB use JavaScript as their scripting and query language in addition to web browsers.
Features of JavaScript
JavaScript has the following characteristics:
- Due to their built-in execution environments, all popular web browsers support JavaScript.
- The syntax and structure of the C programming language are followed by JavaScript. As a result, it is a well-organized programming language.
- Certain types in JavaScript are implicitly cast (depending on the operation), making it a weakly typed language.
- JavaScript is an object-oriented programming language that implements inheritance through prototypes rather than classes.
- It can be interpreted with little weight.
- The case is important in this language.
- Several operating systems, including Windows, macOS, and others, can run JavaScript.
- It gives users good control over their web browsers.
History of JavaScript
The first widely used web browser, Mosaic, was released in 1993. Marc Andreessen founded Netscape in the year 1994. He came to the conclusion that the web required a more dynamic form. As a result, it was believed that HTML received a "glue language" to facilitate web design for designers and part-time programmers. As a result, the company hired Brendan Eich in 1995 with the intention of incorporating the Scheme programming language into the browser. However, the company merged with Sun Microsystems before Brendan could begin, allowing it to compete with Microsoft over web technologies and platforms by incorporating Java into Navigator. Now, there were two languages: The scripting language and Java. In addition, Netscape decided to name the scripting language similarly to Java. It resulted in a "Javascript." Finally, the name "Mocha" was given to the first Javascript code by Marc Andreessen in May 1995. The marketing team later changed the name to "LiveScript." However, in December 1995, the language was finally renamed "JavaScript" for trademark and other reasons. JavaScript was created at that time.
Application of JavaScript
Interactive websites are created with javascript. Most people use it for:
- Client-side validation,
- Dynamic drop-down menus,
- Displaying date and time,
- Displaying pop-up windows and dialog boxes (like an alert dialog box, confirm dialog box and prompt dialog box),
- Displaying clocks etc.
