The first point, represented as [x, y].
The second point, represented as [x, y].
The squared Euclidean distance between the two points.
// Define two points
const point1: T_Point = [0, 0];
const point2: T_Point = [3, 4];
// Calculate the squared distance
const squaredDistance = pointPointSquaredDistance(point1, point2);
console.log(squaredDistance); // 25
// Comparing distances without needing actual values
const point3: T_Point = [6, 8];
const dist1 = pointPointSquaredDistance(point1, point2); // 25
const dist2 = pointPointSquaredDistance(point1, point3); // 100
console.log(dist1 < dist2); // true
Use pointPointDistance if the actual Euclidean distance is required.
Calculates the squared Euclidean distance between two points in 2D space.
This function computes the squared distance (without applying the square root) between two points, which is often used in scenarios where comparing relative distances is sufficient, or performance is critical, as it avoids the computational cost of calculating the square root.
