I am a beginner in the field of web development and seeking help in generating a specific output for a given problem:
var totalRows = 5;
var result = '';
for (var i = 1; i <= totalRows; i++) {
for (var j = 1; j <= i; j++) {
result += i;
}
console.log(result+' ');
result = '';
}
Output:
1
22
333
4444
55555
Expected Output:
1
22
333
55555
88888888
I need assistance in modifying my code to achieve the desired output. Can anyone provide guidance?
If you're working with non-sequential numbers, one approach is to utilize an array and leverage the capabilities of the String.repeat method:
[1, 2, 3, 5, 8].forEach(num => console.log(num.toString().repeat(num)));To display the Fibonacci sequence, you can use the following code snippet:
let current = 1
let last = 0
for (let i = 0; i < 5; i++) {
console.log(Array(current+last).fill(current+last).join(''))
let toLast = current
current += last
last = toLast
}Do you have any thoughts on a sequence similar to the Fibonacci sequence?
let totalNumberOfRows = 5;
let output = '';
for (let i = 1; i <= totalNumberOfRows; i++) {
let nextNum = fibonacci(i + 1);
for (let j = 1; j <= nextNum; j++) {
output += nextNum;
}
console.log(output + ' ');
output = '';
}
function fibonacci(n) {
let resultArray = [0, 1];
for (let i = 2; i <= n; i++) {
const prevNum = resultArray[i - 1];
const prevPrevNum = resultArray[i - 2];
resultArray.push(prevNum + prevPrevNum);
}
return resultArray[n];
}[4, 7, 9, 2, 6].map(num => console.log(num.toString().repeat(num)));Looking for assistance with a javascript and DOM code improvement.
