[JavaScript] JS compares array differences

[Copy link]
Posted on 1/23/2018 1:15:39 PM | | |
Using JS to simply compare the differences between two arrays, namely the part with more arr1 than arr2 and the part with more arr2 than arr1, it is conducive to the dynamic addition and deletion of data.
(Here it is relatively simple, there is no duplicate data in the default 2 arrays, because the project is the comparison guid, so it is the only one)
The general idea is to first arrange the two arrays separately, then compare, remove the common data in the two arrays (leave only one), form an array, and then use this array to compare with the number of two groups;
