When bigwigs and communication suddenly talking about the problem.
It prints a bit in the console.
[] == ![] //true
I face the question mark? ? ? ?
So look empty array is false
But the array is an object, the object is not possible is false ah! !
The case of the array is converted to a Boolean value of true
Access to information discovery: any value compared to the Boolean value, the value will be converted to both sides of the Number.
Yes it is, but why turn into an empty array value is 0 then?
JavaScript look at a table of type conversion
When Number ([]) == false, and it will be based on the table of FIG, content first becomes '0', then compare with false.
and so
