Great points above! From my experience in larger projects, especially where edge cases pop up, using a dedicated library for javascript escape html is the most robust and future-proof approach.

One solid choice is the he (HTML Entities) library:

npm install he

Then in your code:

const he = require('he');

const unsafeString = '<div>This is "unsafe" text!</div>';
const safeString = he.escape(unsafeString);
console.log(safeString); // &lt;div&gt;This is &quot;unsafe&quot; text!&lt;/div&gt;

:white_check_mark: Why this works:

  • Comprehensive: Handles complex Unicode, edge cases, and less common entities beyond the usual suspects.
  • Convenient: Well-maintained and tested — you don’t have to reinvent the wheel.
  • Scalable: Perfect if you’re already using npm or bundlers and want to integrate professional-level solutions.

For production-grade projects or when you want peace of mind, libraries like he are the way to go.
