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

To use the isNumber function from the Lodash library in TypeScript, you need to first install the library using a package manager such as npm or yarn. Once installed, you can import the isNumber function and use it in your TypeScript project.

Here's an example of how to use the isNumber function:

index.ts
import { isNumber } from 'lodash';

const myVar: any = 123;

if (isNumber(myVar)) {
  console.log('myVar is a number');
} else {
  console.log('myVar is not a number');
}

In the above code, we are first importing the isNumber function from the lodash library. We then declare a variable myVar and assign it the value 123 of type any. We then use the isNumber function to check if myVar is a number, and log the appropriate message to the console.

Note that we are using any as the type of myVar. If you know the type of your variable, you can replace any with the appropriate type declaration for better type safety.

That's it! Now you know how to use the isNumber function from the Lodash library in TypeScript.
