      JS !== Java

      Try Javascript some day!

      • We have truthy and falsy! Empty string or null? Yeah, that’s false!
      • Of course we can parse a string to number, but if it’s not a number it’s NaN!
      • null >= 0 is true!
      • Assign a variable with =, test type equality with == and test actual equality with ===. You will NEVER use the wrong amount of = anywhere, trust me!
      • Our default sort converts everything to string, then sorts by UTF-16 code. So yes, [1, 10, 3] is sorted and you are going to live with it.
      • True + true = 2. You know I’m right.
