Prepare the Blocks

This step is straightforward. We use the following JavaScript.

for(i=901; i<1000; i+=2){
   bigdummy[i][0] = new Number(i);
}

The code bigdummy[i][0] = new Number(i), creates a new NumberInstance object, and stores a pointer to this object in the ArrayStorage object corresponding to bigdummy[i]. Figure 5 depicts a portion of the heap after this JavaScript runs.
