Catch Binding

catch binding is now optional with ES2019.

For instance, we can write:

let jsonData;
try {
  jsonData = JSON.parse(str);
} catch {
  jsonData = {};
}

Then we don’t need to get the thrown object in the parentheses after the catch .

However, other kinds of errors that aren’t related to parsing will be silently ignored, since we just set it the jsonData object to an empty object.

Another example would be to get a deeply nested property.
