Javascript cannot release memory._javascript tips

Javascript does not provide absolute control over the use of memory. Therefore, javascript cannot be used to release memory.

I encountered such a situation. When creating an array, we have no way to delete the array and let the data be re-established. Javascript only provides Use the Delete method to clear the variable to empty.

For example:

Var OA=new Array("Hello","Good","Yes")

Delete OA[ 1]

This only sets the value of OA[1] to a null value. That is, the result of OA[1] is undefined.
