Find

Returns the first element that satisfies the test function or returns null

Functional programming

• Typing:

<T extends keyof ObjectInfo<O>>(dataType: T, handler: (value: O[keyof O], key: keyof O) => boolean) => ObjectInfo<O>[T] | null

• Example:

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.find('key', v => v > 10);

    // Result: 'L'

}

Modular programming

• Typing:

<O extends object, T extends keyof ObjectInfo<O>>(object: O, dataType: T, handler: (value: O[keyof O], key: keyof O) => boolean) => ObjectInfo<O>[T] | null

• Example:

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

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

    return find(obj, 'key', v => v > 10);

    // Result: 'L'

}
