range source npm

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

Creates an array of numbers (positive and/or negative) progressing from start up to, but not including, end. If end is not specified it's set to start with start then set to 0. If end is less than start a zero-length range is created unless a negative step is specified.

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

Arguments

  1. [start=0] (number)

    The start of the range.

  2. end (number)

    The end of the range.

  3. [step=1] (number)

    The value to increment or decrement by.

Returns (Array)

Returns the new array of numbers.

// => [0, 1, 2, 3]

_.range(1, 5);

// => [0, 5, 10, 15]

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

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

_.range(0);
