I need assistance with creating an array of variable length based on a dynamic value ranging from 1 to 15. The goal is to populate the array differently depending on the specific value of the variable.
For instance, if the variable's value is 1, I would like to store 'A' in the array. If the value is 6, I want to store 'A', 'B', 'C', 'D', 'E', and 'F'. This pattern continues for different variable values.
Could you please provide guidance on how to accomplish this? Thank you in advance.
let arraySize = 5;
const letters = "LMNOPQRSTUVWXYZ".slice(0, arraySize).split('');
// ["L", "M", "N", "O", "P"]
let arrayLength = 4;
let newArray = new Array(arrayLength);
Alternatively, you can create an array without specifying its size and then simply add a new element to it:
let anotherArray = new Array();
anotherArray.push(NEW_ELEMENT);
Here, NEW_ELEMENT can be any variable, string, or number that you wish to append to the array (it will be added at the end of the array).
Just my two cents. (this function accounts for sizes larger than 26)
<script type="text/javascript>
function createAlphabetArray(size) {
var range = 26;
var arr = new Array();
for (var i = 0; i <= parseInt(size); i++) {
// calculate current index within the range
var j = (i < (range-1) ? i : (i - range * parseInt(i / range)));
// get the character value equivalent to ascii 65 + index (charAt(65)==A)
arr[i] = String.fromCharCode(j + 65);
}
// test
// alert(arr.join(""));
return arr;
}
</script>
let number = 5;
let array = new Array(number);
for (let index = 0;index<number;index++) {
array[index] = String.fromCharCode(65+index);
document.write("array["+index+"] = '"+array[index]+"'<br/>");
}
