How can I check if a browser supports WebAssembly?

Platform: Blazor| Category : General, Tips and Tricks, WebAssembly

You can check whether a type of WebAssembly is an object in global scope, but the global scope is not a feasible one across different JavaScript environments, such as a main browser thread, worker, Node.js.

The more feasible solution is as follows.

 const supported = (() => {
      try {
 if (typeof WebAssembly === "object"
             && typeof WebAssembly.instantiate === "function") {
             const module = new WebAssembly.Module(Uint8Array.of(0x0, 0x61, 0x73, 0x6d, 0x01, 0x00, 0x00, 0x00));
             if (module instanceof WebAssembly.Module)
                 return new WebAssembly.Instance(module) instanceof WebAssembly.Instance;
         }
     } catch (e) {
     }
     return false;
 })();
  
 console.log(supported ? "WebAssembly is supported" : "WebAssembly is not supported");
