strange behaviour of console.log

[thosrtanner]

Not sure if this is the right forum, if not my apologies, and please move it to the right place.

I've just noticed this slightly odd behaviour:

{code}
>>> console.log('x y zz y')
x y zz y
>>> console.log('x "https://www.palemoon.com"')
x "https://www.palemoon.com"
>>> console.log('x https://www.palemoon.com')
"x https://www.palemoon.com"
[/code]

why does the 3rd one get a set of quotes round the whole line?
