Laravel-mix: mix.scripts not working without second argument

[happy-sadan]

• Laravel Mix Version: 2.1.11 (npm list --depth=0)
• Node Version (node -v): v8.11.2
• NPM Version (npm -v): 5.6.0
• OS: Windows 10 Pro

Description:

Despite the documentation authorizing the use of mix.scripts() without a second argument, running npm run dev outputs this error :

AssertionError [ERR_ASSERTION]: mix.combine() requires a full output file path as the second argument.

Before trying to reproduce this error though, I got this error instead :

Not a big issue, docs may get outdated. Just pass second argument and chill

Yeah I ended up checking out more recent documentation and doing just that, thanks !
