What is difference between array.length and array.size ??

Question

difference between size and length of a array

Answer 1

There is no difference. Length is aliased as size, size is an alias of length.

Answer 2

https://ruby-doc.org/core-2.2.0/Array.html#method-i-length
According to documentation, size and length are just aliased to each other, and thus behave identically.
