N.B. I am a complete JavaScript beginner.
My assignment is to create an empty array and assign it to a variable. Then, using a for loop, place the numbers 0 to 5 into the array. Then I need to remove the last number in the array and console.log the result.
Any thoughts on why .pop() isn't working? It works when I use it on an array that I construct without a for loop. Thanks.
var numberList = new Array();
for (let numberList = 0; numberList < 6 ; numberList++)
console.log(numberList);
numberList.pop();
console.log(numberList);You're not pushing anything into the array. Right now, all you do is writing to the console. You need to use Array.push(). Also, you overwrite the numberList array with an integer in your for loop.
var numberList = new Array();
for (let i = 0; i < 6 ; i++) {
numberList.push(i);
}
console.log(numberList);
numberList.pop();
console.log(numberList);You did not add any elements to the array. Use Array#push to do so.
let numberList = new Array();
for (let i = 0; i < 6 ; i++) numberList.push(i);
console.log(...numberList);
numberList.pop();
console.log(...numberList);There are multiple issues in the code.
var numberList = new Array();
for (let index= 0; index< 6 ; index++){
numberList.push(index);
}
console.log(numberList);
numberList.pop();
console.log(numberList);
