how to use the unescape function from the underscore library in typescript

To use the unescape function from the Underscore library in TypeScript, you first need to install Underscore using a package manager, such as npm or Yarn. You can use the following command to install Underscore:

index.ts
npm install underscore
23 chars
2 lines

Once you have installed Underscore, you can import it and use the unescape function as follows:

index.ts
import * as _ from 'underscore';

const escapedString = 'This%20is%20an%20escaped%20string.';
const unescapedString = _.unescape(escapedString);

console.log(unescapedString); // Output: This is an escaped string.
214 chars
7 lines

In the code above, we first import the Underscore library using the import * as _ from 'underscore' statement. We then define a string that has been escaped using URL encoding. We pass this escaped string to the unescape function and assign the result to an unescaped string variable. Finally, we log the unescaped string to the console.

Note that the unescape function is used to decode a URL-encoded string, not to escape special characters for use in HTML. For escaping HTML characters, you should consider using a different function, such as the escape function or a third-party library like he.js.
