Rightward Assignment in Ruby
let's take a quick tour of the new experimental feature in ruby called Rightward Assignments.
We all know that to assign a value to a variable it is mentioned as,
a = 3x + y
this pattern is followed from Mathematics to almost all programming languages. to assign a value to variable we assign Rvalue to Lvalue as indicated above.
while the above pattern has become standardized, it feels somewhat unnatural as we read most of the spoken languages from left to right.
we were not able to do
33 => students
with recent changes, Ruby supports Right ward assignments. let's take a look at some examples below,
5 => x # this is equivalent to x = 5
let's take a look at few more examples,
[155, 44] => height, weight
which is equivalent to
height, weight = [155, 44]
def traits [170, 65] end traits => height, weight
Note : This feature is added in Ruby as an experimental feature. it can be removed if developers are not satisfied with it.
