Assigning a number from one variable to another copies its current value. If the first variable changes later, the copied number does not change with it.
let temperature = 18;
const morningTemperature = temperature;
temperature = 22;morningTemperature is still 18.
The starter copies originalScore before changing it. Predict the value of displayedScore, replace the 0 with your prediction, then run the code to compare.
