It is a programming language that was originally developed in the mid-1990s. It was designed to be used in web browsers to add interactivity to web pages. Today, It is one of the most popular programming languages and is used for a variety of purposes beyond web browsers, such as server-side scripting, mobile app development, and game development.
– Classes: ES6 introduces the class keyword, which can be used to create traditional class-based inheritance hierarchies.
– Arrow functions: A new syntax for defining functions, which can be used to concisely define anonymous functions without binding them to a particular variable name.
– Modules: A standard way of organizing code into self-contained units that can be imported by other modules. This makes it easy to reuse code without having to worry about namespace collisions.
– Promises: A standard interface for representing asynchronous operations, which makes it easier to write code that works with asynchronous data sources such as servers and databases.
The EcmaScript language specification has undergone several major revisions since its initial release in 1997. The most recent standard, ECMAScript 2020, was finalized in June 2020. However, not all browsers have implemented the new standards yet.
It has come a long way since its humble beginnings as a simple scripting language for web pages. In the past few years, It has evolved into a robust and powerful programming language that is used by developers all over the world.
– Code should be easy to read and understand.
– Code should be easy to change and extend.
– Code should be well organized.
– Code should be well tested.
Writing maintainable code is important for several reasons. First, it makes it easier for others to understand and work with your code. Second, it makes it easier to make changes to your code without introducing bugs. Well-organized and well-tested code is more resilient to unexpected changes (e.g., new browser versions).
One benefit is that frameworks can help to provide structure and organization to code. This can be particularly helpful when working on large or complex projects. Another benefit is that frameworks can help to streamline the development process by providing features such as built-in templates and tools for testing and debugging code.
