An array of basic type values and reference type values, and Vue's official API. $remove (Reference)

Today is Mengo doubts.

Does the element in the array also point to the memory address?

This is a case in point.

　　

Wherever A[0],a[2] is, as long as its value is the base type value, it is the comparison of the value, as long as its value is a reference type (object), which is the memory address.

Vue official api:http://cn.vuejs.org/api/#array-_24remove_28reference_29, there is an example of an array. $remove (reference), when the argument is an object, it's all fine. For the base value, it needs to be measured again. For insurance purposes, you can use the Array.splice (index, 1) method and then use the VM. $set trigger the View update (splice can actually trigger the view update, according to Vue's official tutorial).
