how to use the pickby function from lodash in javascript

The pickBy function from lodash is used to filter out an object's properties based on a given predicate function. It returns a new object with only the properties that pass the predicate.

Here's an example usage of the pickBy function in JavaScript:

index.tsx
const _ = require('lodash');

const obj = { a: 1, b: 'hello', c: 3 };
const filteredObj = _.pickBy(obj, (value, key) => {
  return typeof value === 'number';
});

console.log(filteredObj); // { a: 1, c: 3 }

In this example, we import the lodash library and define an object obj with three properties. We then use pickBy to create a new object filteredObj with only the properties that are of type number. The predicate function checks each property's value and key and returns true if the value is a number. Finally, we log the filteredObj, which contains the a and c properties from the original object.
