Handle error from setTimeout

Question

Simple question about try-catch for function in setTimeout

try {
    setTimeout(function () {
        throw new Error(\'error!\');
    }, 300)
} catch (e) {
         


        

Answer 1

A bit strange solution, but sometimes it would be useful maybe...

function globalErrorHandler(e) {
  console.warn('eeee!')
  console.warn(e);
}

const _setTimeoutOriginal = setTimeout;
setTimeout = function(callback, timeout) {
  const args = Array.from(arguments).slice(2);
  _setTimeoutOriginal(function() {
    try {
      callback.apply(this, args);
    } catch (e) {
      globalErrorHandler(e);
    }
  }, timeout);
};

setTimeout(function() {
  throw new Error('error!');
}, 300)
