It's a conventional Nasal hash (imagine it like a namespace), which typically contains callbacks, i.e. functions. Driver hashes are usually nested in an outer hash, where a key can be used to look up the concrete implementation. | It's a conventional Nasal hash (imagine it like a namespace), which typically contains callbacks, i.e. functions.

This is an empty hash named <code>myDriverHash</code>: | |||
<syntaxhighlight lang="nasal"> | |||
var myDriverHash = { | |||
}; | |||
</syntaxhighlight> | |||
To populate the hash, we need to add keys to it - in this case, this can be best accomplisheed by adding strings to it, with a color specifying the value: | |||
<syntaxhighlight lang="nasal"> | |||
var myDriverHash = { | |||
"key1": "value" | |||
}; | |||
</syntaxhighlight> | |||
Different key/value pairs are separated using a comma: | |||
<syntaxhighlight lang="nasal"> | |||
var myDriverHash = { | |||
"key1": "some value", | |||
"key2": "another value", | |||
}; | |||
</syntaxhighlight> | |||
