how to use the forin function from lodash in javascript

To use the forIn function from lodash in JavaScript, you need to install the lodash library in your project first. You can do this using npm:

index.tsx
npm install lodash

Then, you can import the forIn function in your JavaScript file:

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

const obj = {
  a: 1,
  b: 2,
  c: 3
};

_.forIn(obj, function(value, key) {
  console.log(key, value);
});

The forIn function takes two arguments: an object and an iterator function. It iterates over all enumerable properties of the object and calls the iterator function with each value and key. The iterator function can be used to perform some operation on each property.

In the example above, we create an object with three properties, then use the forIn function to log each key-value pair to the console. The result would be:

index.tsx
a 1
b 2
c 3

This is just one of many iteration functions that Lodash provides to make working with JS objects and arrays a lot easier.
