Lodash _.unescape


Lodash is a JavaScript library that provides utility functions for common programming tasks. One of its methods is _.unescape, which is used to unescape HTML-encoded characters.

When data is transmitted over the internet, special characters in the data are often encoded to prevent them from being misinterpreted as code. For example, the greater than symbol (>) is encoded as >. This process is known as HTML escaping.

_.unescape reverses this process by decoding the HTML-encoded characters back to their original form. The method takes a string as input and returns the decoded string.

Here's an example of how to use _.unescape:

const encoded = 'This text contains a < symbol.';
const decoded = _.unescape(encoded);
console.log(decoded); // This text contains a < symbol.

In this example, the encoded variable contains a string with an HTML-encoded less than symbol (&lt;). The _.unescape method is then used to decode the string back to its original form, which is then printed to the console.

_.unescape is a useful method for handling data that contains HTML-encoded characters. It can be used to decode data before rendering it to a webpage, for example.

Overall, _.unescape is a simple and straightforward method that helps to simplify the process of handling HTML-encoded characters in JavaScript.
