======Placeholder Expression======
----

**Placeholder expressions** provide a way to insert dynamic values into [[string|strings]] that will get evaluated at game runtime for displaying to the player or printing to the [[developer console]]. Generally, any sort of expression that can be stored into a variable can also be used in a placeholder expression.

Since placeholder expressions are parsed during a [[script|script's]] execution, they should be used sparingly to avoid potential slowdowns or hesitations. When possible, it's best to first store the expression into a variable and then use [[string|string concatenation]] to generate the desired [[string]].

In regards to usage, the expression must be enclosed using the following syntax consisting of a dollar sign and curly braces:

<code bauxite>
${expression}
</code>

As with [[string|strings]], any double quotation marks in the placeholder expression must be escaped with backslashes.

====Example:====
<code bauxite>
display_message("The value of property ABC is ${global.property[\"ABC\"]}");
</code>
