Movie ticket prices in a big retro-cinema depend on the movie title and on the day of week as shown below:

Write a JavaScript function that calculate the ticket price by movie title and day of week.

The input comes as array of 2 strings:

• The first string holds the movie title
• The second string holds the day of week

Examples:

Input:
The Godfather
Friday

Output:
15

Input:
casablanca
sunday

Output:
10

Input:
Schindler's LIST
monday

Output:
8.50

Input:
SomoMOvie
Ninedays

Output:
error

The output should hold the ticket price or “error” if the title or day of week is invalid.

My code and solution to this interesting movie JavaScript task with some explanations:

• Turn all input values to lowercase to avoid character casing mistakes.
• Check the movie title in if-else-if statement.
• For each movie title check the price in a switch-case.
• Beware of invalid movie titles and invalid days of week. Show “error” in such cases.

```function movieDay(arrStr) {
let movie = arrStr[0].toLowerCase();
let day = arrStr[1].toLowerCase();

let price = 0;
if (movie == "the godfather") {
switch (day) {
case "monday":
console.log(price += 12);
break;
case "tuesday":
console.log(price += 10);
break;
case "wednesday":
console.log(price += 15);
break;
case "thursday":
console.log(price += 12.50);
break;
case "friday":
console.log(price += 15);
break;
case "saturday":
console.log(price += 25);
break;
case "sunday":
console.log(price += 30);
break;
default:
console.log("error");
break;
}
}
if (movie == "schindler's list") {
switch (day) {
case "monday":
console.log(price += 8.50);
break;
case "tuesday":
console.log(price += 8.50);
