I'm trying to change function name by adding an increment number to it's end each time it gets executed, to achieve a new function name each time the code is executed.

<button id="Btn">alert text</button>

function text1(){
    alert("This is text1");
}

function text2(){
    alert("This is text2");
}

function text3(){
    alert("This is text3");
}

var Btn = document.getElementById("Btn");
var i = 1;

Btn.addEventListener("click", function alertText(){

i++;

//bellow line in the first time should be text2()

text+i();

}
