64-70: Consider adding button styling for consistency.The Play/Pause button logic is correct, but it lacks styling classes. Adding Tailwind classes would improve consistency with the rest of the UI.
🔎 Suggested styling improvement
- <button onClick={() => { + <button + className="px-4 py-2 bg-blue-500 text-white rounded-lg hover:bg-blue-600 transition-colors" + onClick={() => { - if(timeLine.paused()) { - timeLine.play(); + if(timelineRef.current?.paused()) { + timelineRef.current.play(); } else { - timeLine.pause(); + timelineRef.current.pause(); } }}>Play/Pause</button>Note: Also added optional chaining (
?.) for safety when accessing the timeline ref.

1-14: LGTM! Clean GSAP implementation.The
gsap.from()animation is correctly implemented using theuseGSAPhook with an empty dependency array to run once on mount. The animation properties are valid and will create a smooth looping animation.src/pages/GsapFromTo.jsx (1)
1-19: LGTM! Correct fromTo implementation.The
gsap.fromTo()animation is properly implemented with distinct from and to states. The animation will smoothly transition the box from the starting state to the end state with looping.src/pages/GsapTo.jsx (1)
1-14: LGTM! Solid gsap.to() implementation.The
gsap.to()animation is correctly implemented with proper hook usage. The combination of translation and rotation creates an engaging animation effect.src/pages/GsapTimeline.jsx (1)
9-28: Animation sequence logic is correct.The timeline animation sequence is well-structured with three distinct stages. Once the timeline creation issue is resolved, these animations will execute properly in sequence.

13-14: No action required — GSAP dependencies are current and secure.Both
@gsap/react@2.1.2andgsap@3.14.2are the latest stable versions available on npm with no known security vulnerabilities. The caret version specifiers allow automatic patching within the current minor version.

Critical: Timeline recreated on every render causing memory leaks.
The timeline is created at the component's top level, which means it's recreated on every render. This causes:
- Memory leaks from unreleased timeline instances
- Unpredictable animation behavior
- Play/Pause button referencing different timeline instances
🔎 Recommended fix using useRef
Import useRef and move the timeline creation inside useGSAP:
-import { useGSAP } from "@gsap/react";
+import { useGSAP } from "@gsap/react";
+import { useRef } from "react";
import gsap from "gsap";
const GsapTimeline = () => {
// TODO: Implement the gsap timeline
- const timeLine = gsap.timeline({
- repeat: -1, repeatDelay: 1, yoyo: true,
- });
+ const timelineRef = useRef();
+
useGSAP(() => {
+ timelineRef.current = gsap.timeline({
+ repeat: -1, repeatDelay: 1, yoyo: true,
+ });
- timeLine.to("#yellow-box", {
+ timelineRef.current.to("#yellow-box", {
x: 200,
rotation: 360,
borderRadius: "100%",
ease: 'power1.inOut',
backgroundColor: "green"
})
- timeLine.to("#yellow-box", {
+ timelineRef.current.to("#yellow-box", {
x: 0,
y: 100,
backgroundColor: "red",
ease: "power1.inOut"
})
- timeLine.to('#yellow-box', {
+ timelineRef.current.to('#yellow-box', {
x:200,
ease: "power1.inOut",
backgroundColor: "blue"
})
}, []);And update the button to use the ref:
<button onClick={() => {
- if(timeLine.paused()) {
- timeLine.play();
+ if(timelineRef.current.paused()) {
+ timelineRef.current.play();
} else {
- timeLine.pause();
+ timelineRef.current.pause();
}
}}>Play/Pause</button>🤖 Prompt for AI Agents
In src/pages/GsapTimeline.jsx around lines 6 to 8: the gsap.timeline is created
at the component top level and thus recreated on every render; move timeline
creation into a stable ref inside your useGSAP hook (import useRef), e.g. create
a timelineRef = useRef(null) and initialize timelineRef.current only once (if
null) with gsap.timeline({ repeat: -1, repeatDelay: 1, yoyo: true }) inside an
effect or the hook initialization; update Play/Pause button handlers to call
timelineRef.current.play()/pause() (or toggle) instead of referencing the
transient variable; remove the top-level timeline declaration and add cleanup on
unmount (timelineRef.current.kill() or clear()) to prevent leaks.

52-58: Consider the necessity of the red top border.Each stagger-box now includes
border-t-4 border-t-red-500styling. If this is purely for visual decoration, it looks fine. However, if it was added for debugging purposes, consider removing it.

1-2: LGTM!The GSAP imports are correctly structured for React integration.
6-19: LGTM!The stagger animation is correctly implemented with appropriate configuration. The
useGSAPhook with an empty dependency array ensures the animation runs once on mount, and the stagger settings create a visually appealing sequential effect.

Remove the obsolete TODO comment.
The stagger animation is now fully implemented, so the TODO comment should be removed.

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

In src/pages/GsapStagger.jsx around line 5 the file contains an obsolete TODO
comment "// TODO: Implement the gsap.stagger() method"; remove that comment line
so the codebase no longer references an already-implemented task and keep the

10-10: Remove the TODO comment.The ScrollTrigger implementation is complete below, so this TODO comment should be removed.
🔎 Proposed fix
- // TODO: Implement the gsap scroll trigger
21-22: Consider using consistent quote style.The rest of the file uses double quotes for strings. For consistency, consider using double quotes here as well.
🔎 Proposed fix
- start: 'bottom bottom', - end: 'top 20%', + start: "bottom bottom", + end: "top 20%",
80-80: Remove trailing whitespace.This line contains only whitespace and should be removed for cleaner code.

1-6: LGTM!The imports and ScrollTrigger plugin registration are correctly implemented.
19-24: No action required. The ScrollTrigger configuration syntax is correct for GSAP 3.14.2. Bothstart: 'bottom bottom'andend: 'top 20%'follow valid GSAP ScrollTrigger syntax patterns where the format is "placeOnTrigger placeOnScroller" (e.g., "top center", "bottom 80%", "top 20%").

Fix incorrect opacity value.
The opacity property should be between 0 and 1, not 100. While this will be clamped to 1, it indicates incorrect usage and should be fixed.
🔎 Proposed fix
- opacity: 100
+ opacity: 1📝 Committable suggestion

🤖 Prompt for AI Agents
In src/pages/GsapScrollTrigger.jsx around line 26, the style uses opacity: 100
which is invalid (opacity must be 0–1); change the value to the intended
fractional value (e.g., 1 for fully opaque or 0.0–0.99 for transparency) so the
property is correct and not relying on clamping.

7-10: Consider adding explicit duration for consistency.While the animation is functional, it lacks an explicit duration property (defaulting to 0.5s). Adding
durationwould make the animation timing more explicit and maintainable.🔎 Optional improvement
gsap.to("#text", { opacity: 1, y: 0, + duration: 0.5, + ease: "power2.out", })
11-19: Minor formatting inconsistency.Line 12 has a formatting issue:
opacity:0is missing a space after the colon. Additionally, consider adding an explicitdurationproperty for clarity.🔎 Optional improvements
gsap.fromTo(".para", { - opacity:0, + opacity: 0, y: 60, }, { opacity: 1, y: 0, + duration: 0.5, delay: 0.5, stagger: 0.4, })
