Do you mainly use JavaScript or TypeScript in your work?

The choice between JavaScript and TypeScript depends on project requirements and personal preferences.

JavaScript is a dynamically typed language widely used for rapid development and prototyping. TypeScript is a superset of JavaScript with support for static typing, which helps catch errors at compile time and improves IDE support.

In a professional environment, TypeScript is often preferred, especially in large projects where reliability and maintainability are important. If the project is small or quick prototyping is needed, JavaScript may be used.

Example of using TypeScript:

function greet(name: string): string {
    return `Hello, ${name}!`;
}

console.log(greet("Alice"));

Thus, if typing and scalability are important in your work, it is better to use TypeScript; otherwise, JavaScript.
