What does camelCase typically avoid when naming variables?

CamelCase is a convention for writing variable names where the first letter of each word is capitalized and no spaces or underscores are used between words. This style enhances readability while avoiding any whitespace characters, which could lead to syntax errors in many programming languages.

For example, instead of writing a variable name as "total sales," in camelCase, it would be "totalSales." The key reason camelCase avoids spaces is that spaces are generally not permissible in variable names in programming languages. Most languages treat a space as a separator between different tokens, so including spaces would result in errors when the code is executed.

Thus, while variable names can technically include numbers, capital letters, or underscores in many programming conventions, the defining feature of camelCase is its avoidance of spaces entirely, ensuring that variable names are both compact and easy to read.
