partITech specializes in creating custom-made websites. Since 2012 we have developed a know-how and deep experience in all aspects of front-end development, notably in JavaScript development.

1. What is JavaScript?

JavaScript is a computer programming language primarily used to develop client-side interactive web applications. It is supported by several web browsers such as Google Chrome, Mozilla Firefox, Microsoft Edge, etc.

JavaScript allows developers to create dynamic features such as interactive forms, animations, visual effects, navigation elements, drop-down menus, slideshows, interactive buttons, and much more. It is often used in conjunction with HTML and CSS to create dynamic and responsive web pages.

Furthermore, JavaScript is also used server-side (with Node.js) to develop complex web applications, such as live chat applications, online gaming platforms, e-commerce applications, real-time collaboration applications, and much more.

2. Why use a JavaScript Framework?

For simple applications or specific use cases, the use of libraries or pure JavaScript code may be the most appropriate. However, it is recommended to use a JavaScript framework in thefollowing situations:

Complex web applications: When you develop a complex web application with multiple features, interactions, and states, using a JavaScript framework can greatly ease development. Frameworks offer predefined structures and design patterns that help manage complexity and organize code more effectively.
Large-scale application development: JavaScript frameworks are particularly useful when working on large-scale projects that require a solid architecture and long-term maintenance. Frameworks provide built-in features for managing state, routing, network requests, form validation, model management, etc., which facilitate the development and maintenance of large-scale applications.
Reusable components: If you plan to develop an application with reusable components, using a JavaScript framework can be beneficial. Frameworks provide mechanisms for creating and managing reusable components, saving time and maintaining consistency in the user interface.
Increased productivity: JavaScript frameworks are designed to improve developer productivity by providing tools, libraries, and predefined conventions. They save time by providing frequently used features, automating certain tasks, and offering a clear structure for development.
Team collaboration: JavaScript frameworks offer a consistent structure and predefined coding conventions, which facilitate collaboration among members of a development team. Developers can work on different parts of the application following the same standards and design patterns, facilitating maintenance and updates.

3. Which JavaScript Framework to use?

Some of the most popular and widely used JavaScript frameworks today are React.js, Angular, and Vue.js. Each of these frameworks has its advantages and disadvantages:

React.js is often appreciated for its simplicity and performance. It focuses on building reusable components, which makes creating interactive user interfaces easier. React.js is very popular and has a large community of developers and available resources.
Angular is a complete framework offering many built-in features for creating complex web applications. It is often used for large-scale projects, and its strict structure and powerful directive system make it a solid choice for enterprise applications.
Vue.js sits somewhere between React.js and Angular in terms of features and complexity. It is known for its ease of learning and intuitive approach to user interface creation. Vue.js is appreciated for its flexibility and lightness, while still being capable of handling larger applications.

It's important to note that choosing the best framework will depend on the specific requirements of your project, your knowledge, and experience. partITech is capable of accompanying and advising you on each of these three frameworks.
