@lvlte @defaude Any of you interested in working on this?

Yep sure, I will take a look next week.

Hey, I wanna do it. Please assign it to me.

@littlefermatlives Please open a pull request and do the changes. I will review it.

If anyone finds some of those and either doesn't want to work on them or don't have to knowledge of the function, feel free to share here so others can do it.

I feel like it would also be a good idea for someone to make a checklist on those files that have been throughly checked for these and don't need any more review.

Hello,
We are working on some improvements to this issue.

@benronkth If you have any questions or face any issues, feel free to ask in this thread.

There is a function called rotate (angleInRadians) in two files, namely:

1. Data-Structures\Vectors\Vector2.js

/**
   * Vector rotation (see https://en.wikipedia.org/wiki/Rotation_matrix)
   *
   * @param angleInRadians The angle in radians by which to rotate the vector.
   * @returns The rotated vector.
   */
  rotate (angleInRadians) {
    const ca = Math.cos(angleInRadians)
    const sa = Math.sin(angleInRadians)
    const x = ca * this.x - sa * this.y
    const y = sa * this.x + ca * this.y
    return new Vector2(x, y)
  }

2. Recursive\KochSnowflake.js

/**
   * Vector rotation (see https://en.wikipedia.org/wiki/Rotation_matrix)
   *
   * @param angleInDegrees The angle by which to rotate the vector.
   * @returns The rotated vector.
   */
  rotate (angleInDegrees) {
    const radians = angleInDegrees * Math.PI / 180
    const ca = Math.cos(radians)
    const sa = Math.sin(radians)
    const x = ca * this.x - sa * this.y
    const y = sa * this.x + ca * this.y
    return new Vector2(x, y)
  }

As you see they should be doing the same operation but there is a conversion happening in the second file const radians = angleInDegrees * Math.PI / 180. Not having this line results in a test fail in Recursive\test\KochSnowflake.test.js. Which function should be kept (or renamed)?

Since the second one is first converting to radians and then essentially running the first function, we can rewrite the second one in terms of the first.
