# JavaScript: Find the maximum difference between any two adjacent elements of a given array of integers

## JavaScript Basic: Exercise-92 with Solution

Write a JavaScript program to find the maximum difference between any two adjacent elements of a given array of integers.

**Visual Presentation:**

**Sample Solution: **

**JavaScript Code:**

```
// Function to find the maximum difference between adjacent elements in an array
function max_difference(arr) {
var max = -1; // Initialize a variable to store the maximum difference
var temp; // Temporary variable to calculate the difference
// Iterate through the array to find the maximum difference
for (var i = 0; i < arr.length - 1; i++) {
temp = Math.abs(arr[i] - arr[i + 1]); // Calculate the absolute difference
max = Math.max(max, temp); // Update the maximum difference
}
return max; // Return the final maximum difference
}
// Example usage
console.log(max_difference([1, 2, 3, 8, 9])); // 5
console.log(max_difference([1, 2, 3, 18, 9])); // 15
console.log(max_difference([13, 2, 3, 8, 9])); // 11
```

Output:

5 15 11

**Live Demo: **

**Flowchart: **

**ES6 Version:**

```
// Function to find the maximum difference between consecutive elements in an array
const max_difference = (arr) => {
let max = -1; // Initialize the maximum difference variable with -1
let temp; // Temporary variable to store the absolute difference
// Iterate through the array to calculate the differences between consecutive elements
for (let i = 0; i < arr.length - 1; i++) {
temp = Math.abs(arr[i] - arr[i + 1]); // Calculate the absolute difference
max = Math.max(max, temp); // Update the maximum difference
}
return max; // Return the final maximum difference
};
// Example usage
console.log(max_difference([1, 2, 3, 8, 9])); // 5
console.log(max_difference([1, 2, 3, 18, 9])); // 15
console.log(max_difference([13, 2, 3, 8, 9])); // 11
```
