Three.js - How can I calculate the distance between two 3D positions?

I've already tried searching several different things on Google. Doesn't seem like I'm able to find anything. Thought I might as well upload a question to Stack Overflow.

Thanks!

Where v1 and v2 are of type THREE.Vector3:

function distanceVector( v1, v2 )
{
    var dx = v1.x - v2.x;
    var dy = v1.y - v2.y;
    var dz = v1.z - v2.z;

    return Math.sqrt( dx * dx + dy * dy + dz * dz );
}

Update: In the r74 release of three.js the method .distanceTo( v ) can be used.

In three.js, to calculate the distance between two 3D positions, use the Vector3.distanceTo() method:

const distance = vec1.distanceTo( vec2 );

In Javascript:

function dist(x0,y0,z0,x1,y1,z1){

deltaX = x1 - x0;
deltaY = y1 - y0;
deltaZ = z1 - z0;

distance = Math.sqrt(deltaX * deltaX + deltaY * deltaY + deltaZ * deltaZ);

return distance;
}
