Creating maintainable JavaScript code is important if want to keep using the code.

In this article, we’ll look at the basics of creating maintainable JavaScript code by improving naming.

Naming

To make our JavaScript code maintainable, we got to make the names descriptive so that we know what they do fro the names.

Also, the case should be consistent so that we won’t be confused with the names.

Variables and function should be camel case,

Camel case means that the name starts with a lower case letter and each subsequent word starts with an uppercase letter.

For instance, these are camel case:

let myName;
const someVariable;
let veryLongName;

They all start with a lower case with subsequent words start with upper case.

Variables and Functions

Variable names are camel case and should start with a noun.

This way, we know what they store.

For example, we can write:

let count = 10;
const firstName = "james";
let isTuesday = true;

to define variables with nouns.

If we define variables with other kinds of words like verbs, then we’ll easily confuse them with functions.
