difference between using conditional and || in js [duplicate]

This question already has an answer here:

• Difference between using a ternary operator or just short-circuit evaluation? 2 answers

When something is undefined there are the following two ways of giving a default value.

I have been wondering for a while what the difference between this:

return {
   name: user.name || 'Raul'
}

and this:

return {
   name: user.name ? user.name : 'Raul'
}

Is there any I should use over another, or side effects I should be aware of?
