x=[“j”,“u”,“l”,“i”,“a”]

such as: string?(x) into “julia”

Hi there,

the function you are looking for is called `join`.

```julia
julia> x=["j","u","l","i","a"]
5-element Array{String,1}:
 "j"
 "u"
 "l"
 "i"
 "a"

julia> join(x)
"julia"

```

Alternatively, `string(x...)` and `reduce(*,x)` work as well.

There is also `join`:

```julia
help?> join(x)
  join([io::IO,] strings, delim, [last])

  Join an array of strings into a single string, inserting the given
  delimiter between adjacent strings. If last is given, it will be
  used instead of delim between the last two strings. If io is
  given, the result is written to io rather than returned as as
  a String.

  Examples
  ≡≡≡≡≡≡≡≡≡≡

  julia> join(["apples", "bananas", "pineapples"], ", ", " and ")
  "apples, bananas and pineapples"

julia> join(["j", "u", "l", "i", "a"])
"julia"

```

Sorry, @fredrikekre I updated my post to include `join` before you posted yours 🙂

BTW, for better readability use backticks `` short code goes here `` or triple backticks ```` longer codeblock goes here ```` to enable syntax highlighting etc. for you code.

You need to interpolate global variables with $ when benchmarking with BenchmarkTooks.jl

An extra use case of `join(x)` over the use of the splat operator for the string concatenation is that `join(x,',')` can also let you include a delimiter (separator)
