# JavaScript: Check whether the first and last elements are equal of a given array of integers length 3

## JavaScript Basic: Exercise-72 with Solution

Write a JavaScript program to check whether the first and last elements are equal of a given array of integers length 3.

Pictorial Presentation:

Sample Solution:

HTML Code:

``````<!DOCTYPE html>
<html>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width">
<title>JavaScript program to check whether the first and last elements are equal of a given array of integers length 3</title>
<body>

</body>
</html>
```
```

JavaScript Code:

``````function first_last_same(nums)
{
var end = nums.length - 1;
if (nums.length >= 1){
return nums[0] == nums[end];
} else {return false;}
}

console.log(first_last_same([10, 20, 30]));
console.log(first_last_same([10, 20, 30, 10]));
console.log(first_last_same([20, 20, 20]));
```
```

Sample Output:

```false
true
true
```

Flowchart:

ES6 Version:

``````function first_last_same(nums)
{
const end = nums.length - 1;
if (nums.length >= 1){
return nums[0] == nums[end];
} else {return false;}
}

console.log(first_last_same([10, 20, 30]));
console.log(first_last_same([10, 20, 30, 10]));
console.log(first_last_same([20, 20, 20]));
``````

## JavaScript: Tips of the Day

Checks if a string is an anagram of another string (case-insensitive, ignores spaces, punctuation and special characters)

Example:

```const isAnagram = (str1, str2) => {
const normalize = str =>
str
.toLowerCase()
.replace(/[^a-z0-9]/gi, '')
.split('')
.sort()
.join('');
return normalize(str1) === normalize(str2);
};
console.log(isAnagram('iceman', 'cinema')); // true
```

Output:

```true
```
