A simple self-calling function can do it. function removeMeta(obj) { for(prop in obj) { if (prop === ‘$meta’) delete obj[prop]; else if (typeof obj[prop] === ‘object’) removeMeta(obj[prop]); } } var myObj = { “part_one”: { “name”: “My Name”, “something”: “123”, “$meta”: { “test”: “test123” } }, “part_two”: [ { “name”: “name”, “dob”: “dob”, “$meta”: { … Read more
You can stringify it. console.log(JSON.stringify(organizations)); if you want some formatting console.log(JSON.stringify(organizations, null, 2));
Pass a reference to the Bar object, like so: class Foo(object): def __init__(self): self.text = “Hello World” # has to be created first, so Bar.__init__ can reference it self.bar = Bar(self) class Bar(object): def __init__(self, parent): self.parent = parent self.newText = parent.text foo = Foo() Edit: as pointed out by @thomleo, this can cause problems … Read more

class Organism(object): def reproduce(self): #use self here to customize the new organism … return Organism() Another option — if the instance (self) isn’t used within the method: class Organism(object): @classmethod def reproduce(cls): return cls() This makes sure that Organisms produce more Organisms and (hypothetical Borgs which are derived from Organisms produce more Borgs). A side … Read more
The short answer for this is, “because that’s what the C++ standard specifies”. Note that you can always specify a constructor that’s different from the default, like so: class Shape { Shape() {…} //default constructor Shape(int h, int w) {….} //some custom constructor }; class Rectangle : public Shape { Rectangle(int h, int w) : … Read more
Yes, there is a way using Object.keys(obj). It is explained in this page: var fruitObject = { ‘a’ : ‘apple’, ‘b’ : ‘banana’, ‘c’ : ‘carrot’ }; Object.keys(fruitObject); // this returns all properties in an array [“a”, “b”, “c”] If you want to get the value of the last object, you could do this: fruitObject[Object.keys(fruitObject)[Object.keys(fruitObject).length … Read more
var newArray = []; var a=[“a”,”b”,”c”]; for(var i=0;i<a.length;i++) if(a[i]!==”a”) newArray.push(a[i]); As of newer versions of JavaScript: var a = [“a”,”b”,”c”]; var newArray = a.filter(e => e !== “a”);
