How to use

In most cases, it is used to initialize or set variables.

The type depends on the data handled by the array.

Clicking on last in the "Expression" tab sets the function name and () in the formula field.

You can change the contents of the function by clicking on the purple icon.

When dynamic content or variables are used in expressions, special specifications are required.

Examples of arguments and results

In this case, array variables [100,200,300] are provided as an example.

IndexValue
0100
1200
2300

For example, last(variables('array')) will result in 300.

Since the array item data type in this example is integer, "Type" should be "Integer".
