4 Naming Conventions used in Programming

4 NAMING CONVENTIONS USED IN PROGRAMMING

Knowing how to name your variables, classes, objects, functions, etc is such an important skill to have as a developer.

Having the right system and approach in place will make or break you code.

HERE ARE 4 CONVENTIONAL TO KEEP IN MIND --->

1. for ARRAYS

- Make variable names plural because arrays consists of more than one item.

DON'T: var flag = ["India", "America", "Philippines"];
DO: var flagNames = ["India", "America", "Philippines"];

2. for BOOLEANS

- Use prefixes like "is", "has", and "can" to help infer the type of variable.

DON'T: var cool = true;
DO: var isCool = true;

3. for FUNCTIONS

- Have two parts to the name - 1) Verb 2) Noun. This because functions perform some type of action on a resource.

DON'T: totalOfCountries(countries);
DO: calculateTotal(countries);

4. WRITING STYLES

- Depending on the language, you should use one case over the others.

var hackUniversity = "@hackuniversity"' //camelCase
var HackUniversity = "@hackuniversity"' //PascallCase
var hack_university = "@hackuniversity"' //snake_case
var hack-university = "@hackuniversity"' //kebab-case
var hackuniversity = "@hackuniversity"' //lazycase
