Object.fromEntries()

The Object.fromEntries() static method transforms a list of key-value pairs into an object.

The Object.fromEntries() method takes a list of key-value pairs and returns a new object whose properties are given by those entries. The iterable argument is expected to be an object that implements a Symbol.iterator method. The method returns an iterator object that produces two-element array-like objects. The first element is a value that will be used as a property key, and the second element is the value to associate with that property key.

Object.fromEntries() performs the reverse of Object.entries(), except that Object.entries() only returns string-keyed properties, while Object.fromEntries() can also create symbol-keyed properties.

Syntax example: Object.fromEntries(iterable)
