Why is my code not creating an array of [0, 1, 2] when I pass the number 3 as a parameter?
const array = [0];
const increment = (num) => {
if (num > 0) {
increment(num - 1);
array.push(num);
}
return;
};
console.log(array);
increment(3);Almost there, your code is almost functioning correctly. The only issue is that you have placed the console.log statement before calling the function.
const array = [0];
const increment = (num) => {
if (num > 0) {
increment(num - 1);
array.push(num);
}
return;
};
increment(3);
console.log(array);Here's a more concise solution using Array.from:
const makeArray = length => Array.from({ length }, (_, i) => i);
console.log(makeArray(3));Here is a recommended code snippet to achieve the desired result:
const list = [];
const countUp = (number) => {
if (number > 0) {
countUp(number - 1);
list.push(number-1);
}
return;
};
countUp(3);
console.log(list);I want to create an effect where hovering over the .hoverarea class will toggle the visibility of .sociallink1, .sociallink2, and so on, with a drover effect. However, my code isn't working as expected. Additionally, an extra margin is automatically ...
