Blind Coding is a challenging programming exercise where developers write code without immediate access to syntax highlighting, auto-completion, or even the ability to see their code while typing. This practice enhances memory retention, logical thinking, and problem-solving skills. It is often used as a training method to strengthen a coder’s understanding of syntax and algorithms. Blind coding competitions push participants to rely on their knowledge rather than tools, improving accuracy and confidence. It is especially useful for sharpening coding efficiency and deepening mastery of a programming language.
