# Problem Can we fit remaining passengers in the bus using JavaScript

JavascriptWeb DevelopmentFront End Technology

## Problem

We are required to write a JavaScript function that takes in three parameters −

• cap − is the amount of people the bus can hold excluding the driver.

• on − is the number of people on the bus excluding the driver.

• wait − is the number of people waiting to get on to the bus excluding the driver.

If there is enough space, we should return 0, and if there isn't, we should return the number of passengers we can't take.

## Example

Following is the code −

Live Demo

const cap = 120;
const on = 80;
const wait = 65;
const findCapacity = (cap, on, wait) => {
let x = 0;
let y = (on + wait);
if(y > cap){
x += (y - cap);
};
if(x < 0){
x = 0;
};
return x;
};
console.log(findCapacity(cap, on, wait));

## Output
