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

To use the tolength function from the lodash library in TypeScript, you can follow these steps:

1. Install the lodash library by running npm install lodash in your project directory.

2. Import the tolength function from the lodash library at the top of your .ts file, like this:

index.ts
import { toLength } from 'lodash';
35 chars
2 lines

3. Use the tolength function wherever you need it in your code like this:

index.ts
const str: string = 'hello world';
const maxLength: number = 10;
const truncated = str.substring(0, toLength(maxLength));
console.log(truncated); // logs 'hello worl'
167 chars
5 lines

In the above code snippet, we use the tolength function to make sure that the maxLength argument is a positive integer. This helps prevent errors when trying to truncate the str string.
