Power Apps Variable. What are the variables in PowerApps?
In programming languages such as c#, JavaScript we always build our logic using variables. But Power Apps is a little different and requires a different approach, Power app automatically recalculate formulas as the input data changes such as excel.
But sometimes only a variable can enable the experience you want
What all are the benefits of using the formula in Power Apps
Other traditional languages such as JavaScript, need to create an event handler and then code for the textbox, but in power apps no code
We know in power apps, where Label1's text is coming from and There's no other way to affect the text of this control. But in the traditional programming language value of the level can be changed from anywhere. This can make it hard to track down when and where a variable was changed.
User can remove the formula easily from level and back to its original value
