Javascript Code Companion-JavaScript Debugging Tool

Example

Reviewing a function that fetches and displays user data asynchronously.

Scenario

A developer submits a piece of code using asynchronous JavaScript. The Companion analyzes the code for potential pitfalls such as error handling and race conditions, and suggests improvements like adding error handling clauses or refactoring the promise structure for better readability and performance.

Example

Optimizing a script that frequently manipulates the DOM.

Scenario

A user submits JavaScript code designed for dynamic content updates on a webpage. The Companion identifies excessive DOM manipulations and suggests using document fragments or batching updates to improve performance.

Example

Identifying a memory leak in an event listener.

Scenario

A piece of code adds event listeners in a loop without removing them, leading to memory leaks. The Companion detects this pattern and advises the developer to remove event listeners appropriately or use event delegation to limit the number of listeners added to the DOM.
