In other words, it is the sum of all values in a given array divided by the total number of values in it.

Mean, also known as arithmetical mean, is a mathematical concept that refers to the average of an array of values given in a set. By the end, you should have a good understanding of Mean and be able to effectively use it in your own projects. In this article, we will cover what Mean is, how to use it in Javascript, the common benefits and uses of Mean, tips and pitfalls to watch out for, and some example code. One of the most useful aspects of Javascript is the ability to use Mean, or the average of an array of values. There are seven in total ( =, +=, -=, *=, /=, %=, **= ), and mastering them all would help you go a long way.Javascript is a powerful scripting language that can be used to create complex web applications and websites. Once you have familiarized yourself with the addition assignment operator (+=) I would recommend practicing the other assignment operators. Using the JavaScript += operator would help increase code readability, and such minor changes would help while working with a group of senior developers. > 7Īs you can see, the values of ‘y’ & ‘b’ have been added to the ‘x’ & ‘a’ respectively. The Output of the above code snippet is as follows.

The assignment operator does the same in a more concise method. Here we are again taking the value on the right (y) and adding & assigning it to the value on the left (x). This method is just a shorter way of writing the following code. In case you are still confused, I shall break it down even further. The syntax of the assignment operator is quite straightforward and does not require any prerequisites. Essentially it replaces the variable = a + b syntax with a += b. This operator is not only used to add numerical values but can also be used to concatenate strings together. This is a very concise method to add two values and assign the result to a variable hence it is called the addition assignment operator. The JavaScript += operator takes the values from the right of the operator and adds it to the variable on the left.
