Module array/range

range

• range(a: number, b?: number, step?: number): any[]

• Creates an array of numbers (positive and/or negative) progressing from start up to, but not including, end. A step of -1 is used if a negative start is specified without an end or step. If end is not specified, it's set to start with start then set to 0.

  Note: JavaScript follows the IEEE-754 standard for resolving floating-point values which can produce unexpected results.

  example

  range(4); //=> [0, 1, 2, 3]

  range(-4); //=> [0, -1, -2, -3]

  range(1, 5); //=> [1, 2, 3, 4]

  range(0, 20, 5); //=> [0, 5, 10, 15]

  range(0, -4, -1); //=> [0, -1, -2, -3]

  range(0); //=> []

  Parameters

  • a: number

  • Optional b: number

    The end of the range.

  • Optional step: number
