How to write better code?

The example has been picked from operationsdashboard/src/Demo/Flight/Preflightdata.js

In order to write better code, we should always think about readiblity of code and nameing conventions. Readibility of code make it easy for new developer to adopt the code and make new changes. For example you can see t5, t4, convertTime2, etc in the code. Any new developer can not understant the code directly, he/she must have to read the entire code and understand it's uses.

Old code
