Strings represent textual information. They are written in Morpho like this:

    var a = "hello world"

Unicode characters including emoji are supported.

You can also create strings using the constructor function `String`, which takes any number of parameters:

    var a = String("Hello", "World")

A very useful feature, called *string interpolation*, enables the results of any morpho expression can be interpolated into a string. Here, the values of `i` and `func(i)` will be inserted into the string as it is created:

    print "${i}: ${func(i)}"

To get an individual character, use index notatation

    print "morpho"[0]

You can loop over each character like this:

    for (c in "morpho") print c

Note that strings are immutable, and hence

    var a = "morpho"
    a[0] = 4

raises an error.

## split
[tagsplit]: # (split)

The split method splits a String into a list of substrings. It takes one argument, which is a string of characters to use to split the string:

    print "1,2,3".split(",")

gives

    [ 1, 2, 3 ]
