The console is one of the most powerful tools for debugging in JavaScript.
It allows developers to print messages, inspect values, and understand what is happening inside their code while it runs.
Professional developers use the console every day to test logic, find bugs, and verify results.
Common Console Methods
- console.log() – prints normal messages
- console.warn() – shows warning messages
- console.error() – shows error messages
- console.table() – displays data in table format
- console.clear() – clears the console
These methods make debugging faster and easier.
console.log() is used to check variable values while the program runs.
It helps confirm that your code is working as expected.
Warnings and errors stand out visually in the console.
They help developers quickly notice important issues.
These examples show how console methods help track program behavior.
By mastering console debugging, students gain a powerful tool to find bugs faster and write more reliable, professional JavaScript code.
