Class Inheritance

The `inherits` helper is used to set up prototype inheritance between two constructor functions. This is useful when you need to create a subclass that inherits from a parent class.

const inherits = require('babel-helpers').inherits;

function Parent() {}
function Child() {
  Parent.call(this);
}
inherits(Child, Parent);

Object Spread

The `objectSpread` helper is used to merge properties from multiple objects into a single object. This is similar to the object spread operator `{...obj}` in JavaScript.

const objectSpread = require('babel-helpers').objectSpread;

const obj1 = { a: 1, b: 2 };
const obj2 = { b: 3, c: 4 };
const result = objectSpread({}, obj1, obj2);
console.log(result); // { a: 1, b: 3, c: 4 }

Async/Await

The `asyncToGenerator` helper is used to transform an async function into a generator function. This is useful for environments that do not natively support async/await syntax.

const asyncToGenerator = require('babel-helpers').asyncToGenerator;

const asyncFunction = asyncToGenerator(function* () {
  const result = yield fetch('https://api.example.com/data');
  return result.json();
});

asyncFunction().then(data => console.log(data));
