error javascript-obfuscator@4.0.0: The engine "node" is incompatible with this module. Expected version "^12.22.0 || ^14.17.0 || >=16.0.0". Got "12.13.1"
error Found incompatible module.

The error message you're encountering indicates a compatibility issue between the javascript-obfuscator module you're trying to use and your current Node.js version. The module requires a Node.js version of either "^12.22.0", "^14.17.0", or ">=16.0.0", but you have "12.13.1" installed.
Here's how you can resolve this:
Upgrade Node.js
You need to upgrade your Node.js to a compatible version. The easiest way to manage Node.js versions is by using nvm (Node Version Manager).
bash
Copy code
nvm install 14.17.0 # for version 14.17.0
or
nvm install 16 # for the latest in the 16.x line
Choose the version that best suits your project requirements.
Switch to the installed Node.js version:
bash
Copy code
nvm use 14.17.0
or
nvm use 16
Verify the Node.js version:
bash
Copy code
node --version
Reinstall Dependencies
After upgrading Node.js, navigate to your project directory and reinstall your dependencies:
bash
Copy code
yarn install
This should resolve the compatibility issue, and yarn install should complete without the error you were encountering. If your project has specific version requirements, make sure the Node.js version you choose aligns with those requirements.
