What's the right way to decode a string that has special HTML entities in it?

Getting comfortable with decoding HTML entities

Apart from the textarea technique, numerous other solutions persist. Here's how to decode with the popular library - he:

import he from 'he'; // Deploying another secret agent 

console.log(he.decode('The &lt;div&gt; tag')); // Outputs: The <div> tag


And sure, sometimes regex comes to the rescue, for instance, converting ' to an apostrophe:

function decodeNumericEntity(str) {
    // Mission: Locate numeric entities and replace them with decoded characters
    // Agent: Regex
    return str.replace(/&#(\d+);/g, (match, dec) => String.fromCharCode(dec));
}

console.log(decodeNumericEntity('We're')); // I spy with my little eye...the word "We're"


Just always remember to double-check your regex decodings!

Reach for the stars: Unusual cases decoding

Working with libraries like he and custom functions from GitHub repositories can be your bonanza when the going gets complicated:

• Strings embedded with diverse HTML entities
• Obsolete or uncommon entities
• Mixing of encoded and free-text
• Astral symbols and other far-flung entities

Your chosen method must ace all these scenarios, even under cross-browser pressures.

Safety first: Secure decoding

Be vigilant about security. Innocuous missteps in the decoding process could invite unnerving XSS vulnerabilities. Ensure your selected method doesn't roll out the red carpet for potential security threats.

The right tool for the job

Ballooning ease of implementation against test coverage and reliability is vital. Check the pulse of the contributions and maintenance activities before committing to a method.

For Node.js, npm packages like he take the heat off encoding/decoding edge cases. jQuery users can leverage htmlDecode and htmlEncode.

Remember to check online demos or test cases to wrap your head around the chosen solution's behavior.
