Common Mistakes to Avoid

Variable Declaration Mistake

One common mistake is neglecting to declare variables using var, let, or const. Beginners often forget this, leading to unintended global variables. To avoid this, always declare variables properly to maintain scope and prevent conflicts.

Incorrect Function Usage

Another frequent error is calling functions without parentheses, which can confuse beginners. This mistake occurs when they think they are referencing the function instead of executing it. Always use functionName() to ensure the function runs as intended.

Improper Event Handling

Many new developers struggle with event handling, often attaching events incorrectly. This can lead to unresponsive elements. To avoid this, ensure you use the correct event listeners and understand the event propagation model in JavaScript.

Ignoring Browser Compatibility

Beginners often overlook browser compatibility issues, leading to inconsistent behavior across different platforms. This mistake can be avoided by testing applications in multiple browsers and using feature detection libraries like Modernizr.
