Why is it that your if statement does not have brackets surrounding the case?
It only executes the first line after it, which is acceptable. However, it is generally considered good practice to enclose your cases in brackets.
Furthermore, within your if statement, you are assigning ' ' to names[i].
You should utilize the double equals operator.
if (names[i] = '')
Change this to:
if (names [i] == ' ')
let cities = ['Cairo', 'Egypt', 'Africa'];Your code is causing issues for several reasons. You forgot to open your if statement with curly brackets {} and also neglected to close it properly. Additionally, the variable i will never be an empty string ''.
Consider this revised code snippet:
for (let i = 0; i < cities.length; i++) {
if (i === 0) {
alert("Go Cairo!");
alert("You're amazing!");
}
}
Keep in mind that arrays start indexing from 0, so ensure your loop starts at index 0 rather than 1.
