## Issue

why it is showing me 36 even though the minimum number is 27

```
var combination = [27, 36]
for (let x in combination) {
if (combination[x] < 50) {
var min = Math.min(combination[x])
}
}
console.log(min)
```

i tried this multiple ways like

```
var combination = [27, 30, 40, 44, 3, 239, 329, 2, 5, 20923, 96]
for (let x in combination) {
if (combination[x] < 50) {
var min = Math.min(combination[x])
}
}
console.log(min) //output-- 5 //it should be 2
```

in this third example i add (-) to 2

```
var combination = [27, 30, 40, 44, 3, 239, 329, -2, 5, 20923, 96]
for (let x in combination) {
if (combination[x] < 50) {
var min = Math.min(combination[x])
}
}
console.log(min) // output-- still 5 // it should be -2
```

again when am adding (-) to other numbers like in -96 or -5 the output was okay (-96) but when im adding (-) to 2 it is not showing me -2 in the output instead it showing me 5

not only in javascript i tried this with lua, php but output was same as js

can anyone explain me why this happen and how solve this

## Solution

You’re not comparing values to determine the minimum, but instead just replacing the `min`

variable with the last number in the array that is smaller than `50`

. This can be fixed as follows:

```
let min = undefined;
for (let x in combination) {
if (combination[x] < 50) {
min = min == undefined ? combination[x] : Math.min(min, combination[x])
}
}
```

Using `filter`

and `reduce`

, this can be made a lot shorter:

```
combination.filter(x => x < 50).reduce((x, y) => Math.min(x, y))
```
