Understanding Node.js versioning is crucial for maintaining the health, reliability, and security of the JavaScript ecosystem, particularly when working with npm packages.

Let's understand it with an example

Lets take my Nodejs version that is 16.20.2 , Now this version have parts as you can see . To understand this lets break down these individually.
-- first part
the last digit of V16.20.2 in this case 2 signifies minor bug fixes and doesn't have much significance, you can update your nodes to latest or can ignore it if the
last digit of the version is chnaged in changelog.

-- second part
now lets go the 2nd part or digit of V16.20.2 that is 20 now this part of the nodejs Versioning siginifies some feature update ,Bug fixes or security updates so
Updating to the version on release is recommended

-- 3rd part

now we have the 3rd part of the version V16.20.2 that is 16 this siginifies major chnage also known as breaking update that means it can break code incase of version mismatch
so its a must to update or use that version while working on application that uses a specific version

Antoher thing in the Node.js versioning is the caret (^) is used in the package.json file to specify a range of compatible versions for a dependency. t indicates that you will accept any version that is compatible with the specified version, up to the next major version.
example :^x.y.z: Allows versions from x.y.z up to, but not including, x+1.0.0.

btw you can always check your node version by typing ```node --version```
