array-step
Step through an array, or an array of arrays.
examples
Works basically like Array.prototype.shift when it is used on an array of non-array objects.
var step = var arr = 0 1 2 3 4 //returns 0, arr = [ 1, 2, 3, 4 ] //returns 1, arr = [ 2, 3, 4 ] //returns 2, arr = [ 3, 4 ] //returns 3, arr = [ 4 ] //returns 4, arr = [] //returns undefined, arr = []This becomes much more useful when it is used with an array of arrays.
var step = var arr = 0 2 4 5 1 3 //returns 0, arr = [ [1, 3], [2, 4, 5] ] //returns 1, arr = [ [2, 4, 5], [3] ] //returns 2, arr = [ [3], [4, 5] ] //returns 3, arr = [ [4, 5] ] //returns 4, arr = [ [5] ] //returns 5, arr = [] //returns undefined, arr = []api
var step = step(arr)
- Takes an array of arrays, or an array.
