Package Exports

@writetome51/get-array-from-property

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@writetome51/get-array-from-property) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

getArrayFromProperty(
property: string,
objects
): any[]

Returns array of values of property found in each of objects.
property is a string that can include dot-notation ( 'property.subproperty.subsubproperty' ) .

Note: property does not have to be an object key. It can also be an array index.
If getting the values of array indexes, here you need to use dot-notation and not
square braces. Example: '1.0' instead of [1][0]

Examples

let people = [
    {name:'Tom', age: 20},
    {name:'Ron', age: 40},
    {name:'Hank', age: 70},
];
getArrayFromProperty('name', people);
   // --> [ 'Tom', 'Ron', 'Hank' ]


let people = [
    {name: {first: 'Tom', last: 'Johnson'}},
    {name: {first: 'Ron', last: 'Thompson'}},
    {name: {first: 'Hank', last: 'Lawrence'}},
];
let names = getArrayFromProperty('name.last', people);
   // --> [ 'Johnson', 'Thompson', 'Lawrence' ]


let numbers = [
    [1,2,3,4],
    [5,6,7,8],
    [9,10,11,12]
];
getArrayFromProperty('1', numbers);
   // --> [ 2, 6, 10 ]


let numbers = [
    [[1,2], [3,4]],
    [[5,6], [7,8]],
    [[9,10], [11,12]]
];
getArrayFromProperty('1.0', numbers);
   // --> [ 3, 7, 11 ]
