How can I check if a browser supports WebAssembly?

Question

With support for WebAssembly coming into all new major browsers, how can I check whether the current browser which is visiting my website supports it?

(Insufficent reputation to comment so....) If you're testing on older browsers the () => syntax is not supported, so it can be done as a function all instead:

function wasmSupported() {
    // try/catch, return false; as in JF Bastien's answer
}
    
if(wasmSupported()) { ... }
