Unraveling Common JavaScript Errors: A Visual Guide

Struggling with JavaScript errors? Let's break down some of the most common ones with clear examples and visual aids! ?????

The following are the 7 types of errors in JavaScript:

1. Syntax Error -

Syntax errors occur when your code doesn't follow JavaScript's syntax rules. These are often the easiest to spot and fix.

Example -

2. Reference Error -

Reference errors happen when you try to use a variable that hasn't been declared.

Example -

3. Type Error -

Type errors occur when a value is not of the expected type.

Example -

4. Eval Error -

Current JavaScript engines and EcmaScript specifications do not throw this error. However, it is still available for backward compatibility. The error is called when the eval() backward function is used.

Example -

5. URI Error -

When the wrong character(s) are used in a URI function, the error is called.

Example -

6. Internal Error -

In the JS engine, this error occurs most often when there is too much data and the stack exceeds its critical size. When there are too many recursion patterns, switch cases, etc., the JS engine gets overwhelmed.

Example -

7. Range Error -

Range errors are thrown when a numeric variable or parameter is outside its valid range.

Example -

Quick Tips to Avoid Errors:

1. Descriptive Variable Names: Prevents reference errors.
2. Type Checking: Ensures proper usage of methods.
3. Debugging Tools: Use browser dev tools for tracing errors.
4. Error Handling: Implement try-catch blocks for graceful error management.
