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

To use the isRegExp function from the lodash library in TypeScript, you need to first install the lodash library and its type definitions using the following commands:

npm install lodash
npm install @types/lodash --save-dev

Once the installation is complete, you need to import the isRegExp function and use it in your code as shown below:

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

const myRegExp = /\d+/;

console.log(isRegExp(myRegExp)); // Output: true
console.log(isRegExp('hello')); // Output: false

In the above code, we first import the isRegExp function from the lodash library using ES6 module syntax. We then define a regular expression myRegExp and pass it as an argument to the isRegExp function to determine whether it is a regular expression or not. The function returns true if the argument is a regular expression and false otherwise.

Note that the @types/lodash package provides type definitions for the lodash library which enable TypeScript to perform type checking and detect errors during compilation. Always remember to install both the lodash library and its type definitions when using lodash with TypeScript.
