Resources

Available resources:

Filter: Returns only the elements of the object that satisfy the test function
Some: Determines whether one of an object's members satisfies the specified test
Every: Determines whether all the members of an object satisfy the specified test
ForEach: Performs the specified action for each element in an object
ForEachAsync: Performs the specified async action for each element in an object
Map: Calls a defined callback function on each element of an object, and returns an array that contains the results.
KeysMap: Calls a defined callback function on each element of an object, and returns an object with the same keys that contains the results.
Sort: Sorts the position of the object's elements
Reduce: Calls the specified callback function for all the elements in an object. The return value of the callback function is the accumulated result, and is provided as an argument in the next call to the callback function
ReduceRight: Calls the specified callback function for all the elements in an object reversed. The return value of the callback function is the accumulated result, and is provided as an argument in the next call to the callback function
Slice: Returns a section of an object
Omit: Returns the elements that did not have their keys specified
Concat: Combines two objects. This method returns a new object without modifying any existing object
Reverse: Reverses the position of object elements
ToString: Turn object into a string
ToArray: Turn object into an array
Join: Joins all elements of an object separated by the specified separator string
Find: Returns the first element that satisfies the test function or returns null
FindLast: Returns the last element that satisfies the test function or returns null
KeyOf: Returns the key of the first occurrence of a value in an object or null
LastKeyOf: Returns the key of the last occurrence of a value in an object or null
ValueOf: Returns the value of an element of an object
Data: Original object elements
Push: Adds or modifies the original object
Length: Number of elements in the original object

Example with Filter Function

Functional programming:

import objectAsArray from "object-as-array";

export default function example() {
    
    const obj = objectAsArray({
        I : 1,
        V : 5,
        X : 10,
        L : 50,
        C : 100,
        D : 500,
        M : 1000
    });

    return obj.filter(v => v > 10 && v < 1000);

    // Result: {L: 50, C: 100, D: 500}

}

Modular programming:

import filter from "object-as-array/filter";

export default function example() {
    
    const obj = {
        I : 1,
        V : 5,
        X : 10,
        L : 50,
        C : 100,
        D : 500,
        M : 1000
    };

    return filter(obj, v => v > 10 && v < 1000);

    // Result: {L: 50, C: 100, D: 500}

}
