Hmm…  
Julia

```julia
A = rand(4, 8);
b = rand(8)';
c = rand(4);
D = @. exp(A ^ b) - log(c)

```

R

```R
A <- matrix(runif(4*8), nrow = 4)
b <- t(runif(8))
c <- runif(4)
D <- exp(A ^ matrix(sapply(b, function(x) rep(x, 4)), nrow = 4)) - log(c)

```

EDIT: @qsong [pointed out](https://discourse.julialang.org/t/not-a-great-example/34402) that this is a better way to write the last line:

```R
D <- exp(A ^ rep(b, each = 4)) - log(c)

```

It gets worse as soon as you add (user defined?) functions that don’t have vectorized versions in R.

I’m presenting a 1-hour “Intro to Julia” session this Friday to a bunch of R users where I work.  
Broadcasting was (and is) going to be one of my major selling points.
