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.
