Difference between forEach and for loop in javascript

In simple terms, according to the below article, and research, it seems that the main differences are:

For Loop

1. It's one of the original ways of iterating over arrays
2. It's faster
3. You could break out of it using this keyword
4. In my opinion its mainly used for calculations with integers (numbers)
5. The parameters are (iterator, counter, incrementor)

ForEach Loop

1. It's a newer way with less code to iterate over arrays
2. Easier to read
3. Lets you keep variable within the scope
4. Lower chance of accidental errors with the i <= >= etc.....
5. The parameters are (iterator, Index of item, entire array)

>> sparseArray = [1, 2, , 4];

>> sparseArray.forEach(console.log, console);
1 0 [1, 2, 3: 4] 
2 1 [1, 2, 3: 4] 
4 3 [1, 2, 3: 4] 

>> for(var i = 0; i < sparseArray.length; ++i) { console.log(sparseArray[i]) };
1
2
undefined
4 

forEach is a recent addition to make expressive list-comprehension style possible in javascript. Here you can see that forEach skips elements that were never set, but the best you can do with a for loop is to check for undefined or null, both of which can be set as values and picked up by forEach. Unless you expect missing values, forEach is equivalent to for loops, but note that you cannot stop early, for which you need every.

forEach is a method on the Array prototype. It iterates through each element of an array and passes it to a callback function.

So basically, forEach is a shorthand method for the use-case "pass each element of an array to a function". Here is a common example where I think Array.forEach is quite useful, compared to a for loop:

// shortcut for document.querySelectorAll
function $$(expr, con) {
    return Array.prototype.slice.call((con || document).querySelectorAll(expr));
}

// hide an element
function hide(el) {
    el.style.display = 'none';
}

// hide all divs via forEach
$$('div').forEach(hide); 

// hide all divs via for
for (var divs = $$('div'), i = 0; i < divs.length; i++) {
    hide(divs[i])
}

As you can see, the readability of the forEach statement is improved compared to a for loop.

On the other hand, a for statement is more flexible: it does not necessarily involve an array. The performance of a normal for loop is slightly better, because there is no function call for each element involved. Despite of this, it is recommended to avoid for loops when it can be written as a forEach statement.

In a forEach loop you don't control the way you iterate over the array. The classic for loop allows you to choose the iteration algorithm as you want (i++; i--; i+=2*i, etc).

However, a forEach loop is much easier to use - you don't need to mess with all the i counting, finding the array[i] object -- JS does it for you.
