JavaScript Can two asynchronous tasks access the same array at the same time?

Suppose you have an array that is modified by one asynchronous process and then you have another asynchronous process that reads from the same array. Modifications and reads are done synchronously. Now the question is, can the read process somehow gain access to the array while it is being modified by write process?

From experience I know that it can't and while synchronous operations are in progress the thread and therefore all the resources (including array) on which it operates will be blocked. Right? But is it logically consequent from the fact that JavaScript is single threaded or it is outlined specifically somewhere in the specs?
