Of course, the glue code also has runtime costs. JavaScript objects must be allocated and garbage collected, strings must be re-encoded, structs must be deserialized. Some of this cost is inherent to any bindings system, but much of it is not. This is a pervasive cost that you pay at the boundary between JavaScript and WebAssembly, even when the calls themselves are fast.

While Apple no longer officially sells last year’s iPad Air, it is still available — and discounted — at various third-party retailers. Right now, the 11-inch model is on sale at Walmart, Target, and B&H Photo in its base configuration with Wi-Fi and 128GB of storage starting at around $499 ($100 off), while the 256GB model is available at Amazon and Target for $599.99 ($100 off).
