I have an expression
[1:5;] .|> [x->x^2, inv, x->2*x, -, isodd]
taken from Julia documentation.
The output is
5-element Vector{Real}:
1
0.5
6
-4
true
Can somebody explain the chain of operations on each elements 1:5 in detail.
I did not understand why 1 is converted to 1 and 5 is converted to true.
What you are doing is equivalent to:
julia> (x -> x^2)(1)
1
julia> inv(2)
0.5
julia> (x -> 2x)(3)
6
julia> -(4)
-4
julia> isodd(5)
true
i.e. you are broadcasting a container with five functions to it over a range with five elements. The first function is then applied to the first element of your range, the second function to the second element etc.
