TypeScript

Modern Frontend

Explanation

TypeScript adds static types so APIs, props, and data models stay clear and safer as projects grow.

Code example

typescript
type Skill = {
  id: string;
  name: string;
  level: "beginner" | "intermediate" | "advanced";
};

function formatSkill(skill: Skill): string {
  return `${skill.name} (${skill.level})`;
}

const react: Skill = { id: "1", name: "React", level: "intermediate" };
console.log(formatSkill(react));
