On Start
An event that runs when the program starts.
The on start is a special event that runs when the program starts, before any other event.
Use this event to initialize your program.
Example
In this example, on start sets a dimmer brightness on the screen and the button handler shows a string.
input.onButtonPressed(Button.A, () => {
basic.showString("Hello!")
})
led.setBrightness(50)
What about JavaScript?
on-start only exists in the block editor. In JavaScript, all code executes sequentially from the first line.
