    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.

    Try Javascript today!
