ECMA International approved the next JavaScript edition called ECMAScript 2019. It will help standardize JavaScript language and foster independent implementations from browser vendors.
The new JavaScript edition contains many proposed changes to field declarations, and methods and fields (for both static and private).
Here are a few critical features of ECMAScript 2019 edition.
- Due to the changes in Functions.prototype.toString, all ECMAScript functions can keep source text without using implementations.
- The method prototype.sort() is now stable. It sorts the array elements in place and returns the array.
- The Symbol.prototype.description property directly exposes the internal slot of a symbol rather than revealing indirectly through Symbol.prototype.toString.
- Users can omit Catch binding when it is unused.
- Object.fromEntries is a new feature that creates or transforms key-value pairs into an object.
- String.trimStart() trims white space from the start of a string.
- Prototype.flatmap provides convenience and optimization. It is now possible to do flattening and mapping in the same operation. Moreover, users don’t need to allocate the mapping array to remove it at the time of flattening.
The development teams can view and download the ECMAScript 2019 specification from the ECMA International website.
