# String Slice Functions
These function operate on or generate slices of strings. In Go, a slice is a
growable array. In Sprig, it's a special case of a `list`.
## join
Join a list of strings into a single string, with the given separator.
```
list "hello" "world" | join "_"
```
The above will produce `hello_world`
`join` will try to convert non-strings to a string value:
```
list 1 2 3 | join "+"
```
The above will produce `1+2+3`
## splitList and split
Split a string into a list of strings:
```
splitList "$" "foo$bar$baz"
```
The above will return `[foo bar baz]`
The older `split` function splits a string into a `dict`. It is designed to make
it easy to use template dot notation for accessing members:
```
$a := split "$" "foo$bar$baz"
```
The above produces a map with index keys. `{_0: foo, _1: bar, _2: baz}`
```
$a._0
```
The above produces `foo`
## sortAlpha
The `sortAlpha` function sorts a list of strings into alphabetical (lexicographical)
order.
It does _not_ sort in place, but returns a sorted copy of the list, in keeping
with the immutability of lists.
