Core Idea

<YouTube minutes={6} href="https://www. youtube.

Key Concepts

• Example: Fade-in effect
• Example: Fade in and out
• Example: interpolate a spring animation
• Example: Prevent the output from going outside the output range
• Example: Scaling feels nonlinear? Use perceptual scale output<AvailableFrom v="4.0.490" />
• Example: CSS transform values<AvailableFrom v="4.0.472" />
• Example: Discrete string values<AvailableFrom v="4.0.509" />
• Example: Numeric tuples<AvailableFrom v="4.0.473" />

Code Examples

const frame = useCurrentFrame(); // 10
const opacity = interpolate(frame, [0, 20], [0, 1]); // 0.5

• What it demonstrates: Usage pattern for interpolate() from the official docs.
