Linear Memory

// Create memory: 1 initial page, 10 max (64KB per page)
const memory = new WebAssembly.Memory({
  initial: 1,
  maximum: 10,
});

// Read/write through a typed array view over the buffer
const view = new Uint32Array(memory.buffer);
view[0] = 42;
view[1] = 100;
console.log(view[0] + view[1]); // 142

// Grow memory (returns the previous page count)
const prev = memory.grow(2);
console.log("grew from", prev, "pages");

// Re-create the view after grow (the old buffer detaches)
const fresh = new Uint32Array(memory.buffer);
