Common Coding Mistakes to Avoid
Even experienced programmers make mistakes.

Undefined variables:

Ensure all variables are declared and initialized before use.

Type coercion:

Be mindful of JavaScript's automatic type conversion, which can lead to unexpected results.

Incorrect scope:

Understand the difference between global and local scope to avoid unintended variable access.

Logical errors:

Carefully review your code for logical inconsistencies that might lead to incorrect output.

Off-by-one errors:

Pay attention to array indices and loop conditions to prevent errors in indexing and iteration.

Infinite loops:

Avoid creating loops that never terminate due to incorrect conditions or missing exit points.

Example:
// Undefined variable error
let result = x + 5; // Assuming x is not declared

// Type coercion error
let age = "30";
let isAdult = age >= 18; // Age will be converted to a number

By being aware of these common pitfalls, you can write more robust and error-free code.
