@types Packages का उपयोग

// npm install --save-dev @types/lodash
// Provides types for the lodash JS library, published under DefinitelyTyped.
console.log("@types packages add compile-time types for untyped JS libraries");

// npm install --save-dev @types/express
// Adds zero runtime code -- only type information used by the compiler.
console.log("Installing @types/express adds no runtime bundle weight");

// After installing @types/lodash:
// import _ from "lodash";
// _.chunk([1, 2, 3], 2); // fully typed and autocompleted
console.log("Typed library calls get full autocomplete and checking");

// axios ships its own types (see its package.json "types" field),
// so `npm install --save-dev @types/axios` is unnecessary.
console.log("Some libraries bundle their own types, skip a separate @types install");

// Check package.json for a "types" or "typings" field first.
// Installing a redundant @types package can create conflicting definitions.
console.log("Always check for bundled types before installing @types separately");
