Recipe Objective

This recipe explains tuples and named tuples in julia.

Tuples And Named Tuples

Julia has an inbuild data structure called a tuple which is similar to function arguments, it returns a value. A tuple can hold any values but it can not be changed. Syntax of tuple consists of parentheses and commas, it can be accessed via indexing.
Named tuple are similar to tuple except we can access them by using a dot.

(2, 3+2)
a = (0.0, "Julia", 5*4)
a[2]

b = (x=3, y=3+5)
b[1]
b.y
