# Digit distance of two numbers - JavaScript

We are required to write a JavaScript function that takes in two numbers a and b returns their digit distance.

## Digit distance

The digit distance of two numbers is the absolute sum of the difference between their corresponding digits.

For example: If the numbers are −

345 678

Then the digit distance will be −

|3-6| + |4-7| + |5-8| = 3 + 3 + 3 = 9

## Example

Following is the code −

const num1 = 345; const num2 = 678; const digitDistance = (a, b) => { const aStr = String(a); const bStr = String(b); let diff = 0; for(let i = 0; i < aStr && i < bStr.length; i++){ diff += Math.abs(+(aStr[i] || 0) - +(bStr[i] || 0)); }; return diff; }; console.log(digitDistance(num1, num2));

## Output

Following is the output in the console −

9
