What does V mean in nodejs version number?

Node.js is a JavaScript running environment based on the Chrome V8 engine. It is popular among developers because of its efficiency, lightweight and cross-platform features. When developing with Node.js, we often encounter version numbers, such as v10.15.3, v12.7.0, etc. Among them, what does the letter V mean? This article will give you the detailed answer.

First of all, it needs to be clear that the letter V is not a fixed version number identifier. There is no official requirement to add the letter V to the version number of Node.js. However, due to historical reasons and convention, v (lowercase) is commonly used as the version number identifier in the Node.js community.

So why does this convention occur? Perhaps this requires us to trace back to the birth and development of Node.js:

The predecessor of Node.js is a prototype system called Node developed by Ryan Dahl in 2009. Over the next year, Node.js was officially released as an open source project. At this time, the version number of Node.js is still very simple "0.1.0".

As Node.js continues to develop, the version number also evolves, such as "0.2.0", "0.3.0" and so on. The use of numbers for version numbers at this stage is completely sufficient, and there is no need to add additional identifiers.

However, as Node.js becomes more and more popular and more and more developers begin to use it, the identification of version numbers becomes more and more important. At this time, the Node.js community is considering introducing a more standardized version number naming method.

So, in the Node.js v0.10.0 version released in 2013, v (lowercase) was used as the version number identifier. In this version number, v represents Version. The reason why v is used instead of other letters may be because v is easier to type on the keyboard keys.

Since then, the Node.js community has generally adopted the convention of v (lowercase) as the version number identifier. At the same time, Node.js has also begun to implement a development model based on stable and unstable versions. Each stable version will have its own name. For example, the stable version of the v12.x series is named Erbium.

In summary, V is not a necessary identifier in the Node.js version number, but a convention in the Node.js community. The use of V as the version number identifier started from version v0.10.0. The reason why V is used is because it is easy to input on the keyboard. With the continuous development of Node.js, the naming method of version numbers is also constantly changing, such as the introduction of stable versions and unstable versions, etc. For different versions, the naming of version numbers is also different.

Finally, it should be noted that although the version number is not a fixed format, in actual development, we still need to name it according to official specifications. Only by distinguishing version numbers according to specifications can our code be better maintained and managed.
