CSS类型对象模型的更改

AudioWorklet

有几个 JavaScript 更改:

The Function.prototype.toString() function now returns exactly what is written in the source code. This includes whitespace and other text that may have been used. For example, if there is a comment between the function keyword and the function name, the comment is now returned in addition to the keyword and name.

JSON is now a syntactic subset of ECMAScript, which allows line separator (U+2028) and paragraph separator (U+2029) symbols in string literals.

The catch clause of a try statement can now be used without a parameter.

String.prototype.trimStart() and String.prototype.trimLeft() are now available as the standards-based way of trimming whitespace from strings, in addition to String.prototype.trim() which was already implemented. The non-standard trimLeft() and trimRight() remain as aliases of the new methods for backward compatibility.

The Array.prototype.values() method returns a new array iterator object that contains the values for each index in the array.
