Why TypeScript Was Developed

TypeScript was developed by Microsoft to address some of the limitations of JavaScript, especially in large-scale applications.

The Need for TypeScript

JavaScript is a dynamic language, which can lead to issues in larger codebases, such as:

• Lack of Type Safety: Bugs related to type errors are common and can be difficult to debug.
• Scalability Issues: Managing large JavaScript codebases can become challenging as they grow.

How TypeScript Solves These Issues

• Static Typing: TypeScript introduces optional static typing, which helps catch errors during development.
• Improved Tooling: TypeScript's type system enables better tooling, such as autocompletion and refactoring support.

Example: Basic TypeScript Code

function add(a: number, b: number): number {
  return a + b;
}

const result = add(1, 2); // TypeScript ensures `result` is a number

Conclusion

TypeScript was developed to help developers write more robust and maintainable code, especially in large and complex applications.
