I need to find a key that contains an object in a. It should not return me a key that contains array or string . For example in a it should return me d but not b or c
a = {"b" : "hi","c":[1,2,3],"d":{"2:":3}};
Here is the snipped I tried. It returns me first instance of Object. But I dont need Array instance just a dict.
var _ = require(underscore);
_.findKey(a,_.isObject);
You can use regular JS for this:
var keysThatContainObjects = Object.keys(a).filter(function(k) {
return typeof a[k] === "object" && !Array.isArray(a[k]);
}); //["d"]
1 line
var keysThatContainObjects = Object.keys(a).filter(function(k) { return typeof a[k] === "object" && !Array.isArray(a[k]); }); //["d"]
length property? Maybe it would be better to use !Array.isArray(a[k])...
k => typeof a[k] === "object" && !Array.isArray(a[k])I very clean way would be to use pick from underscore
var a = {"b" : "hi","c":[1,2,3],"d":{"2:":3}};
var aFiltered = _.pick(a, function() {
return _.isObject(value);
});
_.isObjectwon't work for this, because arrays are objects.
