Some vendors have implemented a conditional catch clause but it’s not a standard and not widely supported in browsers. Throwing errors in other languages If you’ve ever used .NET/Mono you may appreciate how good the error handling behaviour is out of the box, especially for web services. If you are not familiar with the .NET/Mono stack bare with me here for a minute. It has naming conventions for standard errors, like InputValidationException for input validation errors and SecurityException for permissions errors, which is great for encouraging consistency in error handling.
Representing these concepts directly in code comes in two parts: data to represent the state, and functions to represent the behavior. ES6 classes give us a convenient syntax for defining the state and behavior of objects that will represent our concepts. ES6 classes make our code safer by guaranteeing that an initialization function will be called, and they make it easier to define a fixed set of functions that operate on that data and maintain valid state.
It took a while to get here, though — nearly 10 years of standardization work. But the wait is almost over. With the release of Firefox 60 in May (currently in beta), all major browsers will support ES modules, and the Node modules working group is currently working on adding ES module support to Node.js.
