_.range([start=0], end, [step=1])

sourcenpm package

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.

  • end (number): The end of the range.
  • [step=1] (number): The value to increment or decrement by.

Returns

(Array): Returns the range of numbers.

    // => [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(1, 4, 0);
    // => [1, 1, 1]
    _.range(0);
