Inverts the keys and values of an object.
Only own enumerable string keys are processed; symbol keys are ignored. The input object is not mutated.
反转对象的键和值。
仅处理自身可枚举的字符串键，符号键会被忽略。不会修改输入对象。
The type of the keys in the source object. 源对象中键的类型
The type of the values, which become the keys of the result. 值的类型，将成为结果对象的键
The source object. 源对象
A new object with keys and values swapped. 键和值互换后的新对象
When multiple keys share the same value, the later key wins in the result. Symbol values become symbol keys (supported by Object.fromEntries).
Object.fromEntries
当多个键拥有相同的值时，后面的键会胜出。符号值会成为符号键 （Object.fromEntries 支持符号键）。
invert({ a: 1, b: 2 })// => { 1: 'a', 2: 'b' } Copy
invert({ a: 1, b: 2 })// => { 1: 'a', 2: 'b' }
