react-native-bg-thread

This package helps in executing the javascript in a background thread. Time-consuming javascript code is shifted to a native background thread by freeing the main-UI thread, which helps in increasing the efficiency of the application. Thread priority can be handled by passing in the appropriate flags. Currently we support three types of flag as under:

Priority Flags	Description	Android thread value	IOS thread value
MAX	This sets the thread priority to the maximum available on the corresponding native platform.	10	1.0
MIN	This sets the thread priority to the minmimum available on the corresponding native platform.	1	0.1
NORMAL	This sets the thread priority to the default or normal on the corresponding native platform.	5	0.5
