Since 2015, JavaScript has improved immensely.

It’s much more pleasant to use it now than ever.

In this article, we’ll look at the best features of ES2019.

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.
