What is the difference between "i = i + 1" and "i += 1"?

Question

ruby

Is there a difference, or is it the same thing, only abbreviated?

Answer 1

No difference. Ruby does not have i++, and to shorten 'i = i +1' you can use 'i +=1'
You can see the documentation, for example here: https://www.tutorialspoint.com/ruby/ruby_operators.htm

Answer 2

in my opinion, the first creates a new object equal to i + 1 and returns a reference, the second makes an increment for the original object.

Answer 3

no. i++, i=i+1, i+=1

Answer 4

If I'm not mistaken, then i = i + 1 will create 2 objects in memory, and i += 1 will only add one to the variable already in memory
