JavaScript, also abbreviated as JS, is the third core technology of the triangle of web development and the World Wide Web, and the main programming language of modern web browsers. Qlik Sense, leaving the Qlik engine, services, and the repository database aside, is fully based on JavaScript.
Within the world of software development, JS has the following classification attributes as a programming language:
- It's high-level, meaning it's highly abstracted
- It's dynamic, for example, variables can become strings from numbers and vice versa during the execution of the code
- It's weakly typed, meaning it will allow some missing declaration or typos to go through
- It's prototype-based, meaning you can, for example, create prototype objects, and then augment them in due course, adding or remove attributes of an object
- It's multi-paradigm, meaning it supports multiple types of programming paradigms (for example, object-oriented, procedural) even at the same time
As such, JavaScript is very flexible and friendly for beginners to programming. As you don't need to build or compile code before you can run it (the website does this for you), development speed can be much more agile and the feedback loop becomes shorter.
Programming languages which are not compiled languages are called interpreted languages.
With HTML and CSS, continuing the example of a human person, the skeleton and styling have been defined. But so far, it is only a motionless human being. What keeps it going, functioning, dynamic, and responsive is the human brain, and in this example, JavaScript represents exactly that.
