JavaScript - einen Wert für den Deskriptor verschachtelter Schlüsselzeichenfolgen in einem Objekt festlegen

const setNestedProperty = (object, path, value) => {

    if (path.length == 0) {

        return;

    }

    const limit = path.length - 1; 

    for (let i = 0; i < limit; ++i) {

        const name = path[i];

        object = object[name] || (object[name] = { });

    }

    const name = path[limit];

    object[name] = value;

}

​

// Usage example:

​

const object = {

    name: 'John',

    metadata: {

        type: 'json'

    }

};

const myKeyPath = ['metadata', 'key'];

const myKeyValue = 'my-key-value';

​

setNestedProperty(object, myKeyPath, myKeyValue);

console.log(`object.metadata.key='${object.metadata.key}'`);
