Here is the equivalent JavaScript code for the pseudocode:

```
function intersectTriangle(ray, triangle) {
  let edge1 = subtractVectors(triangle.v2, triangle.v1);
  let edge2 = subtractVectors(triangle.v3, triangle.v1);
  let h = cross(ray.direction, edge2);
  let a = dot(edge1, h);
  if (a > -EPSILON && a < EPSILON) {
    return false;  // ray is parallel to triangle
  }
  let f = 1.0 / a;
  let s = subtractVectors(ray.origin, triangle.v1);
  let u = f * dot(s, h);
  if (u < 0.0 || u > 1.0) {
    return false;  // intersection point is outside of triangle
  }
  let q = cross(s, edge1);
  let v = f * dot(ray.direction, q);
  if (v < 0.0 || u + v > 1.0) {
    return false;  // intersection point is outside of triangle
  }
  let t = f * dot(edge2, q);
  if (t > EPSILON) {
    return t;  // ray intersects triangle
  } else {
    return false;  // ray misses triangle
  }
}

function subtractVectors(v1, v2) {
  // Return the difference of two vectors
}

function dot(v1, v2) {
  // Return the dot product of two vectors
}

function cross(v1, v2) {
  // Return the cross product of two vectors
}
