Writing-Clean-Code

“Any fool can write code that a computer can understand. Good programmers write code that humans can understand.” — Martin Fowler’

Writing a clean code is a much-needed skill that every developer should learn. In this article I will share tips to write a clean code.

Clean Variables (How to name variables)

Choosing the best and relevant names for your variables and function will save you lots of time. So, when declaring a variable keep in mind why you are declaring it when it will be used.

For Example:

var a, b
function do(a, b) {
     return a+b
}

the above code will give you the sum of two numbers. But the variables and function names are not explaining what this code does. Let’s see the following example,

var num1, num2
function addNumbers(num1, num2) {
      return num1+num2
}

The above code is completely explaining that a function will take two arguments and will give you the sum of these two numbers.
