refresh behavior in Interface

Appian had concepts of load() and with(),

If you use load(), the code engulfed by load will get evaluated only once. A local variable's value is only calculated the first time the expression is evaluated and is then loaded back into the expression each time the expression is evaluated again within the same context

If you use with(),it recalculates the local variable values after interactions. This recalculation always happens, even if the interaction's updates could not have impacted the variable's value

localVariables() can implement the functionality of load and with function for each local variable initialized using various refresh options in the a!refreshVariable function.

Is there any way to verify the conclusion?

Play around the code to verify

a!localVariables(
  local!counter:0,
  local!randomValue:a!refreshVariable(
    value: rand()
    /*refreshInterval: 0.5*/ /*Refresh every 30 seconds*/
    /*refreshOnReferencedVarChange: local!counter*/  /*Refresh when value of counter changes. Click on Add and see the change*/
    /*refreshAlways: true */  /* Refresh always*/
  ),
  {
    a!linkField(
      links: a!dynamicLink(
        label: "Add",
        saveInto: {
          a!save(
            local!counter,
            local!counter+1
          )
        }
      )
    ),
    a!textField(
      value: local!randomValue
    )
  }
)
