Shared Array Buffers and Atomics As you will see, the ES2017 features, shared array buffers and atomics, are closely related. I'll first make sure we're on the same page for the topics web workers and array buffers in combination with typed arrays. You will need to gain or refresh that knowledge to fully understand shared array buffers and atomics.
Other New Language Features I'm covering the remaining major ES2017 features in this module. You can now iterate over an object in new ways with Object. values and Object. entries. With getOwnPropertyDescriptors or descriptor you can get metadata about the properties of an object. PadStart and padEnd are useful prototype functions of string that let you pad one or more characters before or after an existing string. And trailing commas are in many cases now legal in literals and parameter lists, which has benefits.
