# Finding minimum number of required operations to reach n from m in JavaScript

## Problem

We are required to write a JavaScript function that takes in two numbers, m and n, as the first and the second argument.

Our function is supposed to count the number of minimum operations required to reach n from m, using only these two operations −

**Double**− Multiply the number on the display by 2, or;**Decrement**− Subtract 1 from the number on the display.

For example, if the input to the function is −

const m = 5; const n = 8;

Then the output should be −

const output = 8;

## Output Explanation:

Because the operations are −

5 → 4 → 8

## Example

The code for this will be −

const m = 5; const n = 8; const findOperations = (m, n) => { let res = 0; while(n > m){ if(n % 2 === 0){ n /= 2; }else{ n += 1; }; res += 1; }; return res + m - n; }; console.log(findOperations(m, n));

## Output

And the output in the console will be −
