Essential TypeScript tips for modern web development
Here are some essential TypeScript tips that will help you write better code!
TypeScript is smart enough to infer types in many cases:
// Let TypeScript infer the type
const numbers = [1, 2, 3]; // Type: number[]
const user = {
name: "John",
age: 30,
}; // Type: { name: string; age: number }Always enable strict mode in your tsconfig.json:
{
"compilerOptions": {
"strict": true
}
}Keep your code DRY with type aliases and interfaces:
type UserRole = "admin" | "user" | "guest";
interface User {
id: number;
name: string;
role: UserRole;
}
