Web Development Techdegree Student 13,776 Pointsdefining this._phone in the setter method
Ashley set the value of this._phone as
set phone(phone) {
const phoneNormalized = phone.replace(/[^0-9]/g, "");
this._phone = phoneNormalized;
}
But why didn't she just code it like this -
set phone(phone) {
this._phone = phone.replace(/[^0-9]/g, "");
}
I tried it this last way and it seemed to work fine and just wondering why she took the extra step here.

I believe Ashley took the extra step declaring the phoneNormalized variable to better emphasize the steps we are taking before setting the property.
Similar to how we can be more explicit in declaring functions
function add(num1, num2) {
const sum = num1 + num2;
return sum;
}
Alternatively, we can be more concise and return the value directly without assigning extra variables
function add(num1, num2) {
return num1 + num2;
}
