Problem

What is the difference between the following two code snippets?
Code Snippet 1:
var array = [1,2,3,4,5];
for (var i = 0; i < array.length; i++) {
console.log(array[i]);
}
Code Snippet 2:
var array = [1,2,3,4,5];
array.forEach(function(element) {
console.log(element);
});
The first code snippet uses a for loop to iterate over the array, while the second code snippet uses the forEach method. The forEach method is generally more efficient, because it avoids creating a new scope for each iteration.

Solution

// Code Snippet 1:
var array = [1,2,3,4,5];
for (var i = 0; i < array.length; i++) {
console.log(array[i]);
}

// Code Snippet 2:
var array = [1,2,3,4,5];
array.forEach(function(element) {
console.log(element);
});
