Use descriptive variable names

Avoid single-character variables and abbreviations in favor of descriptive, full-word names that clearly communicate the variable’s purpose or content. This improves code readability and makes the codebase more maintainable for other developers.

Examples of improvements:

• Change x to children in function parameters
• Change str to string for string parameters
• Change e to focusable when iterating over focusable elements

Descriptive names act as inline documentation, making code self-explanatory and reducing the cognitive load for developers reading or maintaining the code.
