- _-___________-_ 7y ago"0123Test" is a better number-containing string for testing, to catch out things that try to interpret the string as a number first and then as a string if that fails. For example, JS's insane parseInt function will give you 123 for "0123Test".
- battery_cowboy 7y agoWow, I learned something in here and I was just "trolling" in the test thread! Thanks!
- yread 7y ago> parseInt("0123Test") 123 > 0123 83 parseInt is actually the adult in the room
- TeMPOraL 7y agoIn a way. The convention is that 0123 is "123" in octal.
- yread 7y agoYes, I know that's why I even tried it in console as I was a bit surprised that parseInt doesn't do octal. Why does js even support octal? I never found octal particularly useful. Speak hexadecimal or die
- sweeneyrod 7y agoBecause C does.
- hurflmurfl 7y ago> parseInt('0123Test', 8) 83 you could do it like this, otherwise it uses the default value for the base parameter.
- TeMPOraL 7y agoThat leading 0 is also useful for the things that try to interpret the string as number first and are able to understand octal.
