Javascript How do i edit and update an object - arrays

Question

New to javascript! What if I want to edit and update an object with pre-existed value?
array [];
// this function is for pre-existed value
function object1 ( mytext ) {
this.text = mytext
}
var usertext = new object ("my text to edit");
memArray.push (usertext);
console.log (usertext)
What about edit/update for prompt value?
function object2(){
var text
this.getData = function(){
return{
text: this.text
}
}
this.setData = function (){
this.text = prompt ("Type anything");
}
return this.setData();
}
var user = new addUserObject;
memArray.push(user.getData());
console.log(memArray);

There's a lot of methods but my method is using "for" iterate to the word you want to edit and change it.
var myArray = ["hello" , "hi"];
console.log(myArray);
function addToArray(str){
myArray.push(str);
}
addToArray("yo");
console.log(myArray);
function editArray(){
var word = prompt("Please enter which word you want to change:", "");
if (word != null && word.length > 0){
var found = false;
for (var i = 0; i < myArray.length; i++){
if (word == myArray[i]){
found = true;
var editWord = prompt("You want to change \"" + word + "\" to:", "");
if (editWord != null && editWord.length > 0){
myArray[i] = editWord;
} else {
console.log("You input nothing.");
}
break;
}
}
if (!found){
console.log("Cannot find this word");
}
} else {
console.log("You input nothing.");
}
}
editArray();
console.log(myArray);
