# JavaScript
Supported OSIntegration version1.0.0
## Overview{% #overview %}

With the Datadog [JavaScript integration](https://app.datadoghq.com/integrations/rum-javascript), resolve performance issues quickly in JavaScript components by:

- Debugging the root cause of performance bottlenecks, such as a slow server response time, render-blocking resource, or error inside a component
- Automatically correlating JavaScript performance data with user journeys, AJAX calls to the server side, and logs
- Alerting your engineering teams when crucial performance metrics for JavaScript (such as Core Web Vitals) fall below a threshold that results in a poor user experience

Monitor your JavaScript applications from end-to-end by:

- Tracking and visualizing user journeys across your entire stack
- Debugging the root cause of slow load times, which may be an issue with your JavaScript code, network performance, or underlying infrastructure
- Analyzing and contextualizing every user session with attributes such as user ID, email, name, and more
- Unifying full-stack monitoring in one platform for frontend and backend development teams
