Given a variable var Number = 2425;, the task is to split it into two parts and store them in separate variables.
var data = 24;
var month = 25;
What would be the most efficient way to achieve this using JavaScript?

Transform the number into a string, then utilize the substring method to extract the necessary characters.
let number = 3037;
let strNum = String(number);
let partOne = strNum.substring(0, 2);
let partTwo = strNum.substring(2);
console.log(partOne, partTwo);To extract the number at a specific position, add a comma after that digit and then combine the remaining digits together. Split the resulting string by commas to create an array. The extracted array can now be used at the specified position. See the solution below
function separateNumber(num, pos) {
var withComma = num.substring(0, pos) + ',' + num.substring(pos);
return withComma.split(',');
}
console.log(separateNumber('2425', 2));
// ["24", "25"]
You may now utilize the elements of the array for your calculation.
One way to tackle this is by converting the number into a string and then using slicing.
let numberValue = 3789;
let strNumber = String(numberValue);
let middleIndex = Math.floor(strNumber.length/2);
let firstPart = Number(strNumber.slice(0, middleIndex));
let secondPart = Number(strNumber.slice(middleIndex));
console.log(firstPart);
console.log(secondPart);Instead of seeing "Number" as a simple value, we can view it as an arithmetic progression with a base of 100:
let number = 2425
let data = Math.floor(number / 100)
let month = number - (data * 100)
console.log(number)
console.log(data)
console.log(month)
/* Result
2425
24
25
*/I find it confusing how "month" could exceed 12 or even reach 11 if starting from a base of 0.
