how to use the conforms function from lodash in javascript

The conforms function in lodash creates a function that checks if an object conforms to a given object shape. It returns a new function that takes an object as an argument, then returns a boolean value indicating whether the object conforms to the given shape or not.

Here's an example usage of conforms:

index.tsx
const users = [
  { name: 'John', age: 30, gender: 'male' },
  { name: 'Jane', age: 25, gender: 'female' },
  { name: 'Jack', age: 40, gender: 'male' },
];

const shape = { name: String, age: Number, gender: String };
const conformsFunction = _.conforms(shape);

// Filter the users array based on whether each user matches the shape or not
const filteredUsers = users.filter(conformsFunction);
console.log(filteredUsers); // [{ name: 'John', age: 30, gender: 'male' }, { name: 'Jane', age: 25, gender: 'female' }, { name: 'Jack', age: 40, gender: 'male' }]
