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

To use the constant function from the lodash library in TypeScript, first, you need to install the lodash library. You can do this by running the following command in your project directory:

npm install lodash --save
26 chars
2 lines

Once you've installed the library, you can import the constant function and use it like this:

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

// Example usage
const myConstant = constant('Hello from the constant function!');
console.log(myConstant()); // Output: "Hello from the constant function!"
193 chars
6 lines

The constant function takes one argument and returns a new function. The returned function will always return the same value, the value that was passed to constant as an argument.

To provide typing support for lodash, install the @types/lodash package by running the following command in your project directory:

npm install @types/lodash --save-dev
37 chars
2 lines

Then, you can simply add the following import statement at the beginning of your TypeScript file:

index.ts
import * as _ from 'lodash';
29 chars
2 lines

This will give you access to all of the lodash functions, including constant, with typing support.
