birds-eye

object or array with nesting → collection containing all primitive value types and corresponding nest depths

Install

npm install --save birds-eye

Usage

Object with nesting:

const obj = {
  i: Math.E,
  j: (n) => n * n,
  k: {
    l: true,
    m: [],
    n: {
      o: {
        p: {
          q: 'Q'
        }
      },
      r: null
    }
  },
  s: 42
}

Nested structure of the object's primitive values:

console.log(birdsEye(obj));

// => 
[ { type: 'number', depth: 0 },
  { type: 'boolean', depth: 1 },
  { type: 'string', depth: 4 },
  { type: 'null', depth: 2 },
  { type: 'number', depth: 0 } ]

Return all primitive types found at a given depth of nesting:

console.log(birdsEye.atDepth(obj, 0)); // => ['number', 'number']
console.log(birdsEye.atDepth(obj, 42)); // => []

This of course also works with nested arrays:

const arr = [2,[42,[[[true]]],'n',[1e6]], undefined];
console.log(birdsEye(arr));

// =>
[ { type: 'number', depth: 0 },
  { type: 'number', depth: 1 },
  { type: 'boolean', depth: 4 },
  { type: 'string', depth: 1 },
  { type: 'number', depth: 2 },
  { type: 'undefined', depth: 0 } ]

API

birdsEye(obj)

Arguments

• obj - object|array to map to a one dimensional collection

birdsEye.atDepth(obj, n)

Arguments

• obj - same as above
• n - the nest depth that the resulting collection should be filtered by
