What is the translation of "so" in French, and how is it used?

Question

How is the conjunction "so" (i.e. It was a beautiful day, so the children played outside) translated in French, and is there a particular construction I need to do?

Answer 1

C'était une belle journée, alors les enfants sont sortis jouer dehors.

Even better would be : si bien que les enfants...

Answer 2

'alors' means 'so.'

Answer 3

"donc"

It was a beautiful day, so the children played outside  -> C'était une belle journée, donc les enfants ont joué dehors.

donc + subject + verb + ... (like a normal sentence, no special structure, no inversion or whatsoever)

Answer 4

"Alors" or "donc"
