Doesn't understand insertion/deletion in the middle of a list

Left: [1,2,3,4]
Right: [1,2,4]

Expected outcome:

• Missing element 2 from the array on the right side

Actual outcome:

• Both sides should be equal numbers [ed: element 2]
• Missing element 3 from the array on the right side

Hello @andreareina. Thank you for using JSONDiff.

In this case you have two arrays that look like this:

Element	Left Side	Right Side
0	1	1
1	2	2
2	3	4
3	4	missing

In this case there are two differences between these two arrays. The first difference is that the second elements have different values: The left-side value is 3 and the right-side value is 4. The second difference is that the right-side array is missing the third value.

This would be a little easier to see if the arrays had different values. Like this:

Left: ["apple", "banana", "orange", "pear"]
Right: ["apple", "banana", "pear"]

Element	Left Side	Right Side
0	apple	apple
1	banana	banana
2	pear	orange
3	orange	missing

In this case the two difference would be:

Both sides should be equal strings

and

Missing element 3 from the array on the right side

Does that help explain what's going on here and why you see two difference instead of one?
