```julia
replace(s::AbstractString, pat=>r; [count::Integer])

```

[https://docs.julialang.org/en/v1/base/strings/#Base.replace-Tuple{AbstractString,%20Pair}](https://docs.julialang.org/en/v1/base/strings/#Base.replace-Tuple%7BAbstractString,%20Pair%7D)

If I want to make two replacements in one pass I have to use regex? It seems like I should be able to do

```julia
replace("hello world", "hello" => "hi", "world" => "julia")

```
