Completing this task is simple with a basic for loop.
We can set the number to 10 and initialize an empty array. The for loop will iterate through and populate the array, ending with the output in the console log.An alternative method is:
By using Array.from with a new Array and a function that maps each element accordingly, we achieve the same result.In this snippet, we define the number as 10 and directly create the array using Array.from, resulting in the same numerical sequence printed via console log.Imagine having a variable called num that represents the total number of elements in an array as well as the value of the last element.
let num = 8;
Next, create an empty array to store the numbers.
let numbers = [];
Using a for loop, populate the array with numbers starting from 1 up to the value of num.
for (let j = 0; j < num; j++)
numbers.push(j+1);
This will fill the array numbers with values ranging from 1 to 8.
