PS: the above globally changes the console's behavior and has the side
effect that log calls made from unrelated JavaScript code will also no
longer show the "source file". The clean way is probably to define the
Module's "print" function by passing a respective object into the Module
constuction function:
let in = {
print: function(t) {
// suppress annoying "source file" info
setTimeout(console.log.bind(console, t)); // "lose" the original context
}
};
