angular.toJson( obj, pretty );
angular.fromJson( json );
vs
JSON.stringify( obj )
JSON.parse( json )
I used to use native ones, but started to use angular ones for consistency. Any other reasons to use those?

My first thought was it's related to some test purposes(same case with using $window instead of window). But after looking into source code: https://github.com/angular/angular.js/blob/master/src/Angular.js#L977
function toJson(obj, pretty) {
if (typeof obj === 'undefined') return undefined;
if (!isNumber(pretty)) {
pretty = pretty ? 2 : null;
}
return JSON.stringify(obj, toJsonReplacer, pretty);
}
Looks like it's a simple wrap for case with undefined object as param.
same for fromJson: https://github.com/angular/angular.js/blob/master/src/Angular.js#L998
function fromJson(json) {
return isString(json)
? JSON.parse(json)
: json;
}
so, generally, it's just to remove that checking from app code into framework code.
