Facebook Engineering has rolled out a new witty combination of language and platform development in form of HHVM and Hack programming language which is providing production jobs at Baidu, Box, and Wikipedia.
The change in programming is getting more attention as well as the hack on the Top of virtual machine engine has raised web-based workloads. Hack’s has contributed to allow users to navigate through all languages as the workloads are based on demands.
Earlier it was defined to typed language like javan and c# or dynamic type JavaScript, Python, or Perl. The Facebook’s service side is very efficient as the operations are based upon such ideas and there is a central component for Facebook’s service-side operations.
First the code is written then it is checked whether it is correctly typed or not. The advantage with dynamic language is at runtime you will get notified of any error in the code written.
Whereas Hack lies between the two as it is type language which has a gradual process. It is dependent upon programmer decision to use it statically or Dynamically or at fine grained level , they can customized it according to their need as told by Julien Verlaguet who is a software engineer at Facebook.
The advantage and ability is code base running on HHVM may look oversimplified and easy. It also comes handy as it boost speed that can extents to other programming environments. The motive of hack is not much about language but about the iterative process that will be followed by writing a code and changing the code when an error is detected.
It makes the entire process more productive and efficient it gives developers a nice pace and simply the entire process. The hack type is not a binary that is restricted to only command line whereas it works at the backend watching the files in the background. So whenever it is started it consumes all the files and whatever that needs to be changed will be recognized on background server which provides constant refreshing data and maintain a check on all files with superfast services.
There is much inefficiency on development side when it comes to fixing code problems like Testing, debugging and editing.
Such inefficiency makes it very chaotic and time taking which is further resolved by hack as the error code gets yellow which needs to be fixed and developers gets to know it quickly and hack enable developer to quickly navigate through the yellow area of code to fix it as soon as possible.
The other advantage of Hack list is it reduces the waiting time of CPU as it makes it easy to fetch data and re-order and perform operations it has its own algorithm to work on efficiency as explained by Verlaguet.
She notes that the time-saving potential here adds up at scaled that defines many of Facebook’s development projects that have added efficiency at scale and found their way into more mainstream enterprise worlds.
The new approach to programming will be combining Hack and HHVM programming. The expectations are high as Hack will reach to PHP based services which is now used at Facebook and has become a defacto language. The more such programming tools and approaches will make their own way in a broader world.
