30. Equal II

The code outputs the following:

true
true
true
true
false
true
true
true
true
false
true
true

Explanation:

• [1] == 1: true, because the array gets converted to its first element (which is 1) and compared to the number 1.
• [1] == '1': true, because the array gets converted to its first element (which is 1) and then the string '1' gets converted to the number 1, which they both match.
• ['1'] == '1': true, because the string '1' gets converted to the number 1, which matches the array's first element (which is also 1).
• ['1'] == 1: true, for the same reason as above.
• [1] == ['1']: false, because arrays are compared by reference, not by value. These two arrays have different memory locations, so they are not equal.
• new Boolean(true) == 1: true, because the boolean object gets converted to the primitive value true, which is equal to the number 1.
• new Boolean(true) == new Boolean(true): true, because both objects get converted to their primitive value of true, which is equal.
• Boolean(true) == '1': true, because the boolean value of true gets converted to the string '1', which matches.
• Boolean(false) == [0]: true, because the boolean value of false gets converted to the number 0, which matches the array's first (and only) element.
• new Boolean(true) == '1': false, because the boolean object gets converted to the primitive value true, which is not equal to the string '1'.
• new Boolean(false) == [0]: true, for the same reason as before.
• null == undefined: true, because both null and undefined are falsy values and are loosely equal to each other.
