how to use the identity function from lodash in javascript

To use the identity function from lodash in JavaScript, first, you need to install the lodash library using npm or yarn. After that, you can import the identity function from the lodash module and use it as shown below:

index.tsx
// import the identity function from lodash
const { identity } = require('lodash');

// pass any value to the identity function
console.log(identity('hello')); // output: 'hello'
console.log(identity(123)); // output: 123
console.log(identity(true)); // output: true
console.log(identity(null)); // output: null
console.log(identity(undefined)); // output: undefined
console.log(identity({ name: 'John' })); // output: { name: 'John' }

The identity function simply returns the input value as it is, so it can be useful as a default or fallback function.
