WebSince it is an integer array, each of its element will occupy 4 bytes of space. Hence first element occupies memory from 10000 to 10003. Second element of the array occupies immediate next memory address in the memory, i.e.; 10004 which requires another 4 bytes of space. Hence it occupies from 10004 to 10007. WebAssembler declaration of integer variable assigns a label to a memory space allocated for the integer. The variable name becomes a label for the memory space.
