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

To use the truncate function from the lodash library in TypeScript, you need to first install the lodash library and the TypeScript type definitions for it (if you haven't already done so):

npm install lodash
npm install @types/lodash
45 chars
3 lines

Then, you can import the truncate function from lodash and use it in your TypeScript code like this:

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

const str = 'Lorem ipsum dolor sit amet, consectetur adipiscing elit.';
const truncatedStr = truncate(str, { length: 20 });

console.log(truncatedStr); // "Lorem ipsum dolor sit..."
218 chars
7 lines

Here, we imported the truncate function from lodash with import { truncate } from 'lodash'.

We then passed a string str and an options object to the truncate function. The length property of the options object specifies the maximum length of the truncated string.

The truncate function returns the truncated string, which we then log to the console.

Note that you may need to configure your TypeScript compiler options to include the lodash typings in your project. You can do this by adding the following line to your tsconfig.json file:

{
  "compilerOptions": {
    "types": [ "lodash" ]
  }
}
57 chars
6 lines

This ensures that the TypeScript compiler knows about the lodash library and its types, so you can use them in your code without errors.
