dimensionality
Find the number of dimensions of an array
npm install dimensionality --save
Usage
dimensionality(array[, shallowSearch = false])
Returns the maximum array depth of the array, meaning the maximum number of nests in the nested arrays.
var dimensionality = require('dimensionality');
dimensionality(undefined) // 0
dimensionality(4) // 0
dimensionality([2, 4, 5, 2]) // 1
dimensionality([undefined, null, 2, {}, 'test']) // 1
dimensionality([undefined, null, 2, {}, 'test', []]) // 2
dimensionality([[{}, ['test']]]) // 3
dimensionality([1, [2, [3, [4]]]]) // 4
// shallowSearch example
dimensionality([[4, [5]]]) // 3
dimensionality([[4, [5]]], true) // 2
dimensionality([
[[1, 2], [3, 4]],
[[5, 6], [7, 8]],
], true) // 3
ShallowSearch
By default, shallowSearch = false
.
If shallowSearch = true
, then dimensionality finds the dimension only searching for the first element of the nested array.
This is useful for large data structures that are known to have equal array depth.
