# Comparisons with the && (logical AND) operator

---
## Problem Explanation
· _Combine the two if statements into one statement which will return `"Yes"` if `val` is less than or equal to `50` and greater than or equal to `25`. Otherwise, will return `"No"`._


---
## Hints

### Hint 1
The logical AND (`&&`) operator compares both statements and returns `true` only if both are true or can be converted to true (truthy).


### Hint 2
Remember that this effect can be also achieved by nesting `if` statements.

## Solutions

```javascript
function testLogicalAnd(val) {
  // Only change code below this line

  if (val <= 50 && val >= 25) {
    return "Yes";
  }

  // Only change code above this line
  return "No";
}

// Change this value to test
testLogicalAnd(10);
```

#### Code Explanation
The function first evaluates `if` the condition `val <= 50` evaluates to `true` converting `val` to a number if necessary, then does the same with `val >=25` because of the logical AND (`&&`) operator; if both return true, the `return "Yes"` statement is executed.
