How can I prevent getting 'undefined' as the last output when using console.log() with a looping construct?
let array = ["Fiji", "Santorini", "Bora Bora", "Vancouver"];
let arrayLength = array.length;
for(let index = arrayLength; index >= 0; index--)
{
console.log(array[index]);
}
Resolved by updating:
let arrayLength = array.length - 1
index >= 0;
In response to @Pointy's observation, it's important to note that the "greater equal" operator in JavaScript is represented as >=, not =>. Additionally, it is essential to initialize the index variable as let index = arrayLength-1 since JavaScript indexes start at 0, making the index of the last item in the array one less than the length of the array. The corrected code snippet is as follows:
let array = ["Fiji", "Santorini", "Bora Bora", "Vancouver"];
let arrayLength = array.length;
for(let index = arrayLength-1; index >= 0; index = index - 1)
{
console.log(array[index]);
}
