Recipe Objective

This recipe explains what is anonymous functions in julia.

Anonymous Functions

In julia functions are termed as first-class objects because we can assign them to variables, these can be called using a standard function call. We can also create them anonymously without actually giving them a name by using either of the shown examples.

a -> a^2 + 2a + 1
function (a)
    a^2 + 2a + 1
end
map(round, [4.5, 2.6, 3.1])
map(a -> a^2 + 2a + 1, [3, 2, 1])
