Invalid number: number in octal form

[grunjol]

the same way you write 0xFF as hexadecimal (and it validates), should standard allow 0755 be a valid number in octal representation?

In webtorrent/webtorrent-desktop#326 ended up using parseInt('0755',8)

iirc there is some inconsistency between runtimes so it's better to just not use it...

@mafintosh Do you remember the simple way to use octals that we came up with?

[feross]

@grunjol You can actually prefix the number with 0o and it will be treated as octal in ES6.

    > 0xFF // ES5: hexadecimal
    255
    > 0b11 // ES6: binary
    3
    > 0o10 // ES6: octal
    8

We can use ES6 freely in WebTorrent Desktop since it's an Electron app and there's no old browsers to worry about :)

great!
