Like a V8 (eight-cylinder) car engine, Chrome V8 is fast and powerful. V8 translates JavaScript code directly into machine code* so that computers can actually understand it, then it executes the translated, or compiled, code.
What is V8 stand for?
The V stands for the shape of the engine, and the 8 stands for the number of cylinders in the engine. So, a V8 engine means a V-shaped engine with a total of 8 cylinders. In a regular engine, the cylinders – usually four of them – are aligned in a row.

Are V8 engines good?
V8 Engines Are an Excellent Balance of Performance and Efficiency. One of the benefits of a V8 engine is its balance of power output and torque. … Larger engine configurations, such as the 12 cylinder, typically have a high power output but are very large in size, heavy in weight and thirsty.
Is a V6 better than a V8?
In comparison to a four-cylinder engine, V6 engines offer more power and run smoother. … Lastly, V6 engines can provide more stability and better handling than their V8 counterparts. V8 Engine. V8 engines typically offer better power and acceleration.
