All you have to do is add the string elements to the function.
Instead of
function typeAndErase(textElement){
let interval
let timeInterval = 100
let typeStrings=["Bruno Prado","Website Designer","Wix Coder"]
Do this -
$w.onReady(() => {
typeAndErase($w("#text26"), "Bruno Prado", "Website Designer", "Wix Coder") //Just the function call
})
function typeAndErase(textElement, text1, text2, text3) {
let interval
let timeInterval = 150
let typeStrings = [text1, text2, text3]
This way you can call the typeAndErase function with any parameters.
