There are two possible solutions to add new properties to an object.
Let’s take a simple object to explain these solutions.
var object = {
key1: value1,
key2: value2,
};
1. Using dot notation: This solution is useful when you know the name of the property
object.key3 = “value3”;
2.Using square bracket notation: This solution is useful when the name of the property is dynamically determined.
obj[“key3”] = “value3”;
