What is vue source code used to write?

Vue source code is written in TypeScript

Vue source code is written in TypeScript, which is a strongly typed superset of JavaScript. TypeScript aims to make JavaScript more maintainable and readable by adding a type system.

Why Vue chooses to use TypeScript

Vue decided to use TypeScript mainly for the following reasons:

• Better types Check: TypeScript's type system helps detect errors during development, thereby improving code quality and stability.
• Better code reusability: TypeScript allows the creation of reusable types and interfaces, which makes code easier to maintain and organize.
• Better IDE support: TypeScript is widely supported by most modern IDEs, which provides advanced features such as code completion, error detection, and refactoring.
• Compatibility with JavaScript: TypeScript is a superset of JavaScript, which means existing JavaScript code can be easily integrated into TypeScript projects.

Advantages of using TypeScript

Using TypeScript to develop Vue source code brings the following advantages:

• Improve the code Maintainability: TypeScript's type system helps reduce errors and simplify code refactoring.
• Reduce debugging time: TypeScript’s type checking feature helps detect and fix errors during development, thereby reducing debugging time.
• Better documentation: TypeScript code uses type annotations, which provides documentation of the code and helps other developers understand the code.
• Greater code reusability: TypeScript allows the creation of reusable types and interfaces, which makes code easier to maintain and reuse.
