What are Global Value Providers in lightning components?

Global value providers are global values and methods that a component can use in expressions.

First we will see how to use $Browser global value provider to check the browser I am running my lightning component.

Output is:

Similarly, you can check browser information in a client-side controller using $A.get().

({

    checkBrowser: function(component) {

        var device = $A.get("$Browser.formFactor");

        alert("You are using a " + device);

    }

})

Similarly, you can check locale information in a client-side controller using $A.get().

({

    checkDevice: function(component) {

        var locale = $A.get("$Locale.language");

        alert("You are using " + locale);

    }

})
