I have published a blog titled : 10 Julia Recipes You Can’t Miss . Please suggest alternate or efficient methods to recipes or additionally what and all other recipes that can be included in the list.

This trick is absolutely brilliant. Is the semicolon before x = rand() necessary. I could run the code without it.

Thank you. I think you are right, it seems like the ; is not necessary, it works without it for me as well even on old versions of Julia.

(x = something, y = something_else) for constructing NamedTuples has been around since 1.0. The novelties since then were (; x, y) for constructing a NamedTuple from variables in scope (instead of having to write (x=x, y=y)) in 1.5, and then applying that to destructuring, i.e. (; x, y) = something …

julia> abc = (a=1, b="hello", c = 3.14) (a = 1, b = "hello", c = 3.14) julia> ac = NamedTuple{(:a, :c)}(abc) (a = 1, c = 3.14) """ keepkeys(nt::NamedTuple, syms::Tuple{Vararg{Symbol}}) Construct a subset of `nt` using only the keys in `syms`. """ keepkeys julia> keepkeys(nt::NamedTuple, ks=NT…

[image] GHTaarn: sqrt(p.x^2 + p.y^2) hypot(p.x, p.y) is nicer

Only if you are familiar with that function; otherwise the formula is unambiguous and hence preferable.

When I have to use a for-loop to get an output, I find really useful to initialize the vector as a keyword argument. Example: function foo(x) output = similar(x) for i in eachindex(x) output[i] = x[i] + 1 end return output end instead, I use function foo(x; output =…

I like that because the output appears in the function statement: a very handy heads-up for the user.

-100. It is worth it to fire up the Julia REPL just to use this nice function and avoid the pain of writing the square root of the sum of the squares.

+100=0. Sorry, I need a bit of context…
