Question

What is the fastest JavaScript engine? Does it really matter?

Answer 1

For production, you don’t have to worry about which JavaScript engine is the fastest. Your page should work in all common browsers, period.

However, in some projects, where you can choose which browsers should support (for example, hobby projects or projects for internal use), you will find that the performance in different browsers varies greatly.

Well, it depends. For whom? As an end user, it matters; I would rather have a browser as fast as possible.

As a developer, he should not, if you do not want to return to the section "It is better done with ...". You should target the most important browsers.

You should probably consider adding more details to your question until it is related to programming.
