Explanation:

• `[] == 0` compares an empty array to 0 using loose equality, which coerces the empty array into an empty string and 0 into a number. An empty string and 0 both have a falsy value, but since they're of different data types, they're not equal. However, when a falsy value is compared to a number, it's coerced into a number, thus resulting in 0. Therefore, `[] == 0` becomes `"" == 0`, which becomes `0 == 0`, evaluating to true.

• `[] == false` also uses loose equality, but this time the empty array is coerced into a falsy value (empty arrays are also falsy), and false is a falsy value. Both have the same type, so they're compared after conversion. Therefore, `[] == false` becomes `0 == 0`, which evaluates to true.

• `!![]` uses the double negation operator (!!), which coerces any value into a boolean by first negating it, and then negating it again. Since an array is a truthy value, its negation is false, and the negation of that is true. Therefore, `!![]` evaluates to true.

• `[1] == 1` uses loose equality, and since the array has a single element, that element is gotten and compared to 1. Because loose equality converts arrays to strings and converts non-string values to strings, `[1] == 1` becomes `"1" == "1"`, which evaluates to true.

• `!![1]` works like `!![]`, and since any non-empty array is truthy, `!![1]` also evaluates to true.

• `Boolean([])` is a function call that returns the boolean value of the argument. Since an empty array is falsy, `Boolean([])` evaluates to false.

• `Boolean(new Boolean([]))` uses the Boolean constructor to create a boolean object, which is a truthy value, so `Boolean(new Boolean([]))` evaluates to true.

• `Boolean(new Boolean(false))` creates a boolean object with a value of false. Since any object is truthy, `Boolean(new Boolean(false))` evaluates to true.
