+# Function Parameters
+
+How to use parameters to pass info in and out of an function.
+
+### @parent js/function
+ 
+
+A [function](/js/function) can have multiple input parameters and/or a single output parameter.  The parameters must be one of the supported variable [types](/js/types).
+
+When you first [create a function](/js/function), it looks like this: 
+```
+export function doStuff() {
+}
+```
+
+### Add a function parameter
+
+1. Open your script (if needed) and then click `script` in the upper-right corner.
+
+2. Under **code** click your function name.
+
+3. Click the function name in your code (this opens the function panel).
+
+4. Click **add input parameter** or **add output parameter**. The parameter is added to your function.
+
+#### Input parameters
+
+The default type for an input parameter is [Number](/reference/types/number):
+
+```
+export function oneInput(p: number) {
+}
+```
+
+To change the default type, click the type ([Number](/reference/types/number) in this case) and change it to [String](/reference/types/string), [Boolean](/reference/types/boolean), or [Image](/reference/image/image). You can add multiple input parameters to a function.
+
+#### Output parameter
+
+the default type for an output parameter is [Number](/reference/types/number):
+
+```
+export function output() : number {
+    let r: number
+    return 42
+    return r
+}
+```
+
+To change the default type, click the type ([Number](/reference/types/number) in this case) and change it to [String](/reference/types/string), [Boolean](/reference/types/boolean), or [Image](/reference/image/image).
+
+### Inputs and output function
+
+The following sample function has two inputs and one output parameter (all are the Number type):
+
+```
+export function inputsAndOutput(p: number, q: number) : number {
+    let r: number
+    return p + q
+    return r
+}
+```
