Variable Utilities

Type declaration

• calculateAverage: ((arr) => number)

  • • (arr): number

    • calculate the average of an array of numberss

      Parameters

      • arr: number[]

        an array of number whose average has to be calculated

      Returns number

      the average

• calculateDistance: ((p1, p2) => number)

  • • (p1, p2): number

    • Calculate the distance betweeen two points

      Parameters

      • p1: Point

        the first point

      • p2: Point

        the second point

      Returns number

      the distance between the points

• calculateSquaredDistance: ((p1, p2) => number)

  • • (p1, p2): number

    • Calculate the squared distance between two points

      Parameters

      • p1: Point

        the first point

      • p2: Point

        the second point

      Returns number

      the squared distance between the two points

• getRandomSubset: ((arr, n) => any[])

  • • (arr, n): any[]

    • get a random subset of something from a array of things must provide the number of things we want from that array

      Parameters

      • arr: any[]

        the array from which the subset has to be made

      • n: number

        number of items to select

      Returns any[]

      a new array made up of a random sample from the original array

• getRandomSubset_map: ((map, n) => Map<any, any>)

  • • (map, n): Map<any, any>

    • This is a super useful method to get a random number of edges or something that you would like to draw this is primarily done because there are way too many edges sometimes and and the number of edges is really What slows the whole rendering process down

      Parameters

      • map: Map<number, any>

        the map that youd like to reduce

      • n: number

        the fraction of items that youd like to return from this map

      Returns Map<any, any>

      A reduced map with a fractio of those many entries
