Do you mainly code in TypeScript or sometimes in pure JavaScript?

I mainly prefer to write in TypeScript because it provides static typing, which helps catch errors at compile time and improves code support in large projects.

However, there are situations where I use plain JavaScript:

• Quick prototypes or small scripts where setting up TypeScript is excessive.
• Working with libraries or environments that do not support TypeScript.

Example of using TypeScript:

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

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

TypeScript increases reliability and development convenience, especially in team projects.
