The advantage that the V8 engine brings in

The V8 engine was developed by Google and was open sourced in 2008. As we all know, JavaScript is an interpreted language and it will not be as efficient as a compiled language, as each line of code gets interpreted one by one while the code gets executed. The V8 engine brings in an efficient model, where the JavaScript code is first interpreted and then compiled into machine-level code.

The new V8 5.9 provides a stable release that introduces TurboFan compiler which provides performance and mass optimization benefits. It also launches Ignition interpreter which is quiet efficient for all the small and big devices like servers or IOT devices etc that varies on memory spectrum. Due to such low memory footprint it delivers fast startup of an application. We can study benchmarks in following link : https://goo.gl/B15xB2

With two powerful updates, the v8 team is also working on Orinoco, which is a garbage collector that works on mechanism of parallel and concurrent compacting.

Such a high performance with promising results was the reason to push the node 8(LTS) launch date from may 2018 to october 2018. Currently we are using node 8 with a non-LTS version. It provides clean replace for users using node v4.x.x and above with no broken library. The version 8 also has various inbuilt features like buffer improvements and inbuilt promisify methods etc. We can study them in following link : https://goo.gl/kMySCS
