Our JavaScript Tutorial is intended for both beginners and experienced programmers. JavaScript is used to create dynamic client-side pages.
JavaScript is a lightweight and cross-platform object-based scripting language.
JavaScript is a translated language, not a compiled language. The JavaScript Translator (which is embedded in the browser) is in charge of translating JavaScript code for web browsers.
What exactly is JavaScript?
JavaScript (js) is a lightweight object-oriented programming language that is used to script webpages on many websites. When applied to an HTML document, it is an interpreted, full-fledged programming language that enables dynamic interactivity on websites. It was first used in 1995 to add programmes to webpages in the Netscape Navigator browser. It has since been adopted by all other graphical web browsers. Users can use JavaScript to create modern web applications that allow them to interact without having to reload the page every time. The traditional website makes use of js to provide various levels of interactivity and simplicity.
However, JavaScript is not compatible with the Java programming language. When Java was becoming popular in the market, the name was suggested and provided. Databases such as CouchDB and MongoDB, in addition to web browsers, use JavaScript as their scripting and query language.
JavaScript Characteristics
JavaScript has the following features:
- Because they include built-in execution environments, all popular web browsers support JavaScript.
- JavaScript is structured and syntaxed similarly to the C programming language. As a result, it’s a structured programming language.
- JavaScript is a weakly typed programming language in which certain types are implicitly cast (depending on the operation).
- JavaScript is an object-oriented programming language that uses prototypes for inheritance rather than classes.
- It is a simple and interpreted language.
- The language is case-sensitive.
- JavaScript is supported by a variety of operating systems, including Windows, macOS, and others.
- It gives users excellent control over web browsers.
JavaScript’s Development
Mosaic, the first widely used web browser, was released in 1993. Marc Andreessen founded Netscape in the year 1994. He recognised the need for the web to become more dynamic. As a result, a ‘glue language’ was thought to be added to HTML to make web design easier for designers and part-time programmers. As a result, in 1995, the company hired Brendan Eich with the intention of implementing and embedding the Scheme programming language into the browser. But, before Brendan could begin, the company merged with Sun Microsystems to incorporate Java into its Navigator, allowing it to compete with Microsoft in web technologies and platforms. There were now two languages: Java and the scripting language. Furthermore, Netscape chose a name for the scripting language that was similar to Java’s. It resulted in ‘Javascript’. Finally, in May 1995, Marc Andreessen coined the term “Mocha” to refer to the first Javascript code. The name was later changed to ‘LiveScript’ by the marketing team. However, due to trademark issues and other factors, the language was finally renamed ‘JavaScript’ in December 1995. JavaScript was born as a result of this.
JavaScript application
JavaScript is a programming language that is used to create interactive websites. It is primarily employed for:
- Validation on the client side,
- Drop-down menus that are dynamic,
- Date and time are displayed.
- Displaying dialogue boxes and pop-up windows (like an alert dialogue box, confirm dialogue box and prompt dialogue box),
- Displaying clocks, for example.
JavaScript Example
<script>document.write(“This is JavaScript example by coderazaa”); </script>
The first JavaScript example is explained in detail in the following chapter.
Prerequisite
