how to use the clonewith function from the lodash library in typescript

To use the cloneWith function from the Lodash library in TypeScript, you need to install both Lodash and its types package. You can do this by running the following command in your project directory:

npm install lodash @types/lodash --save

Once you have installed these packages, you can use the cloneWith function in your TypeScript code like this:

index.ts
import * as _ from 'lodash';

interface MyObject {
  a: number;
  b: string;
  c: boolean;
}

const myOriginalObject: MyObject = {
  a: 1,
  b: 'hello',
  c: true,
};

// Define a customizer function to customize the cloning behavior.
function myCustomizer(value: any) {
  if (_.isBoolean(value)) {
    // Return a new boolean with the opposite value.
    return !value;
  } else {
    // Return undefined to fall back to the default cloning behavior.
    return undefined;
  }
}

// Use cloneWith to create a deep clone of the object, applying the
// customizer function to each value.
const myClonedObject = _.cloneWith(myOriginalObject, myCustomizer);

console.log(myOriginalObject);    // { a: 1, b: 'hello', c: true }
console.log(myClonedObject);      // { a: 1, b: 'hello', c: false }

In this example, we define an interface MyObject with three properties a, b, and c. We then create an object myOriginalObject of this type, and define a customizer function myCustomizer which negates boolean values and falls back to the default cloning behavior for other types.

We then use the cloneWith function from Lodash to create a deep clone of myOriginalObject, applying our customizer function to each value. Finally, we log both the original object and the cloned object to the console to verify that the cloning worked as expected.
