Discussion on: Accessing Nested Objects in JavaScript

[Itachi Uchiha]

I use extract method for my project. Purpose can be different. These codes from my localization project on Github.

github.com/aligoren/local.js/blob/...

 extract(propertyName, object) {
        const parts = propertyName.split(".");
        let length = parts.length;
        let i;
        let property = object || this;

        for (i = 0; i < length; i++) {
            property = property[parts[i]];
        }

        return property;
    }

Usage:

const locals = {
    "tr": {
        "btn": {
            "welcome": {
                "text": "Merhaba hoşgeldin"
            },
            "other": "Diğeri"
        }
    },
    "en": {
        "btn": {
            "welcome": {
                "text": "Hi Welcome"
            },
            "other": "Other"
        }
    }
}

this.extract('btn.welcome.text', locals['tr'])

This is great and easily readable. Maybe we should benchmark all the ways to access nested objects and spread the word so the community will know which one to use and when.

Take a look at i18n library, works in this way.
