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

To use the trimEnd function from the Lodash library in TypeScript, first, you need to import the Lodash library into your project. You can do this by installing Lodash via npm and then importing it into your TypeScript file, as shown below:

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

Once you have imported Lodash, you can use the trimEnd function to remove whitespace from the end of a string, as shown below:

index.ts
const str: string = '   Hello world!   ';
const trimmedStr = _.trimEnd(str); // '   Hello world!'
98 chars
3 lines

In this example, the str variable holds the value " Hello world! ". The trimEnd function is then used to remove the whitespace from the end of the string, resulting in the trimmedStr variable holding the value " Hello world!".

Note that trimEnd is only available in Lodash v4.0.0 and later. If you need to use an earlier version of Lodash, you can use the trimRight function instead, which performs the same operation.
