Remove Property from an Object CODE 
var car =  new Object();
car.model = "Honda Fit";
car.year = 2004;
car.color = "Blue";
Now remove property: 

delete car.year;  // or delete car["year"];
The delete operator deletes both the value of the property and the property itself. Note: 
If we use delete on an array, it will create a sparse array

How to create objects? CODE
1) With keyword 
new
: 

var car =  new Object();
car.model = "Honda Fit";
car.year = 2004;
car.color = "Blue";
2)Using an Object Literal 

var car = {model :"Honda Fit", year :"2004", color:Blue};
3) 

var car = {};
car.model = "Honda Fit";
car.year = 2004;
car.color = "Blue";
4) Using the Object.create method 
var animal1 = Object.create(Animal);
animal1.displayType(); // Output:Invertebrates
5)Using a constructor function Define the constructor function. 
function Car(make, model, year) {
  this.make = make;
  this.model = model;
  this.year = year;
}
then create an object called mycar: 
var mycar = new Car('Honda', 'Fit', 2004);

breadcrumb separator
We can remove or change the breadcrumb separator by assigning different value to 
$breadcrumb-divider: none;
sass variable. We can even assign SVG icon using the following syntax
$breadcrumb-divider: url(data:image/svg+xml;base64,PHN2ZyB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciIHdpZHRoPSI4IiBoZWlnaHQ9IjgiPjxwYXRoIGQ9Ik0yLjUgMEwxIDEuNSAzLjUgNCAxIDYuNSAyLjUgOGw0LTQtNC00eiIgZmlsbD0iY3VycmVudENvbG9yIi8+PC9zdmc+);
If we want to remove the separator, we assign 
none
to the variable
$breadcrumb-divider: none;
