1. When comparing the object and Boolean object converted to a string, then converted to digital, a digital direct conversion Boolean
[] == false
The result is to true, [] is converted to a string '', then converted to a digital 0, is converted to a digital 0 to false
2. Objects and strings are compared, the object is converted to a string, and then compares the two
[1,2,3] == '1,2,3'
The result is to true [1,2,3] into ', 2,3'
3. Object and a digital comparator, the object into a string, and then converted to digital, and then compares the digital
[1] == 1
The result is true, [1] is converted to '1' and then converted to a
And a digital comparator 4. string, the string is converted to a digital
'1' == 1
5. strings and Boolean values are compared, both then compare values all converted into
'1' == true
6. Boolean and as a number, is converted to a digital Boolean
true == 1

Compare special
== undefined null // true comparison returns true null and undefined, and both the other comparison values returned to false Number The ( null ) // 0
