Executing these low-level operations purely within standard JavaScript execution threads often causes significant lag. To solve this, developers use . Popular native C/C++ emulation cores—such as DeSmuME or melonDS—are compiled into Wasm modules. JavaScript is then used as the high-level orchestration layer to manage user interfaces, capture gamepad inputs, read local files, and render textures via WebGL or the Canvas API. Leading JavaScript Nintendo DS Libraries and Projects
As he explored the world of JavaScript, Alex discovered that it was possible to create a basic emulator using the language. He found libraries like WebAssembly and Emscripten, which allowed him to compile C++ code (often used for emulation) into JavaScript. to handle the heavy lifting while using JS

JavaScript, on the other hand, is single-threaded (kind of), garbage-collected, and historically slow. So why target it?
The bottom screen of the DS uses a resistive touchscreen. You can capture mouse or touch events on your canvas and convert them into the 12-bit ADC (Analog-to-Digital Converter) coordinates expected by the ARM7 processor. javascript
