Introduction
JavaScript is a powerful programming language that can be used to manipulate numbers in a variety of ways. One of the most common tasks is to separate a number into its individual digits. This can be done using a variety of methods, depending on the desired outcome. In this article, we will discuss how to separate a number using JavaScript. We will look at different approaches, such as using the modulo operator, using the Math.floor() function, and using the String.split() method. We will also discuss how to convert the separated digits into an array. By the end of this article, you will have a better understanding of how to separate a number using JavaScript.
Solution
//Using the split() method
let number = “1234567890”;
let numberArray = number.split(“”);
console.log(numberArray); // Output: [1, 2, 3, 4, 5, 6, 7, 8, 9, 0]
Since your numbers are 2 digits max you can try this approach.
First divide the number by 10 then for example if we divide 21 by 10 we get 2 and some reminder with math.floor we get rid of the reminder just 2 is left then we multiply 2 by 10 we get 20 that is the first part.
The second part just use % on the the number to get the reminder so for example 21 % 10 it would be 1
var numbers = [20, 21, 22];
var numberSeperator = function(number){
return [Math.floor(number / 10) * 10, number % 10];
}
for(var i = 0; i < numbers.length; i++){
console.log(numberSeperator(numbers[i]))
}

If you’re looking for a way to separate numbers using JavaScript, you’ve come to the right place. Separating numbers is a common task in programming, and JavaScript provides a number of ways to do it. In this article, we’ll look at three different methods for separating numbers in JavaScript.
Method 1: Using the split() Method
The split() method is a built-in JavaScript function that can be used to separate a string into an array of substrings. To use it, you pass in the string you want to split and a separator character. The separator character is used to determine where the string should be split. For example, if you wanted to separate a string of numbers into individual numbers, you could use the comma (,) as the separator character.
For example, let’s say you have a string of numbers like this:
var numbers = “1,2,3,4,5”;
You can use the split() method to separate the numbers into an array like this:
var numbersArray = numbers.split(“,”);
The resulting array would look like this:
[“1”, “2”, “3”, “4”, “5”]
Method 2: Using the match() Method
The match() method is another built-in JavaScript function that can be used to separate a string into an array of substrings. To use it, you pass in the string you want to split and a regular expression. The regular expression is used to determine where the string should be split. For example, if you wanted to separate a string of numbers into individual numbers, you could use the following regular expression:
/\d+/g
For example, let’s say you have a string of numbers like this:
var numbers = “1,2,3,4,5”;
You can use the match() method to separate the numbers into an array like this:
var numbersArray = numbers.match(/\d+/g);
The resulting array would look like this:
[“1”, “2”, “3”, “4”, “5”]
Method 3: Using the for Loop
The for loop is a powerful tool for iterating over an array of elements. It can also be used to separate a string into an array of substrings. To use it, you pass in the string you want to split and a separator character. The separator character is used to determine where the string should be split. For example, if you wanted to separate a string of numbers into individual numbers, you could use the comma (,) as the separator character.
For example, let’s say you have a string of numbers like this:
var numbers = “1,2,3,4,5”;
You can use the for loop to separate the numbers into an array like this:
var numbersArray = [];
var numberString = numbers.split(“,”);
for (var i = 0; i < numberString.length; i++) {
numbersArray.push(parseInt(numberString[i]));
}
The resulting array would look like this:
[1, 2, 3, 4, 5]
As you can see, there are a number of ways to separate numbers using JavaScript. Each method has its own advantages and disadvantages, so it’s important to choose the one that best suits your needs. Hopefully, this article has given you a better understanding of how to separate numbers using JavaScript.
