The following ECMAScript proposal is at stage 3: “Trailing commas in function parameter lists and calls” by Jeff Morrison. This blog post explains it.

The ECMAScript proposal “String padding” by Jordan Harband & Rick Waldron is part of ECMAScript 2017. This blog post explains it.

The following ECMAScript proposal is at stage 4: “Object.values/Object.entries” by Jordan Harband. This blog post explains it.

This blog post explains the so-called TC39 process, which governs how ECMAScript features are designed, starting with ECMAScript 2016 (ES7).

This blog post examines three ways of executing function sequentially:

• Synchronously
• Asynchronously, via Promises
• Asynchronously, via the library co

The ECMAScript 6 specification defines in which order the properties of an object should be traversed. This blog post explains the details.

This is a list of a few ECMAScript 6 features and what their influences were:

This blog post describes the proposed ECMAScript feature “call constructor” (stage 1).

In ECMAScript 6, accessing a let or const variable before its declaration (within its scope) causes a ReferenceError. The time span when that happens, between the creation of a variable’s binding and its declaration, is called the temporal dead zone.

For more information, consult Sect. “The temporal dead zone” in “Exploring ES6”. Here, I’d like to answer two questions:

• Why is there a temporal dead zone?
• Why does typeof cause a ReferenceError for a variable in the TDZ?
