VectorDistance

Returns the distance between two points.

Splits the arguments array into two points. Use Array.prototype.reduce(),Math.pow() and Math.sqrt() to calculate the Euclidean distance between two vectors.

const vectorDistance = (...coords) => {
    let length = Math.trunc(coords.length/2);
    let sum = coords.slice(0,length).reduce((accumulator,currentValue,currentIndex) => accumulator + (Math.pow(currentValue-coords[length+currentIndex],2)),0);
    return Math.sqrt(sum);
}
