CamelCasing Variables
Camel casing is a programming convention used to improve readability and maintain consistency within codebases. In camelCase, the first letter of the first word is lowercase, and subsequent words are capitalized.
Example:
let userFirstName = "John";
let totalAmountDue = 125.00;
Why Use CamelCasing?
- Readability: Makes variables easy to read and understand at a glance.
- Consistency: Provides a standard naming convention across your codebase, reducing confusion.
- Reduces Errors: Minimizes the chance of typos or inconsistent naming.
Best Practices:
- Always start variable names with a lowercase letter, e.g.,
userName, totalCount.
- Do not include spaces, underscores, or dashes, e.g., avoid
user_name or total-count.
- Use descriptive and clear variable names, e.g.,
totalMonthlyRevenue instead of totMonRev.
- Keep consistency across the project, making it easier for teams to collaborate.
