In ES6, there are several ways to add properties to an object.<\/p>\n

    \n
  1. Use the dot operator (.) to directly add properties to an object. For example:<\/li>\n
  2. Create an object with two properties: property1 with value ‘value1’ and property2 with value ‘value2’.<\/li>\n
  3. Using square bracket operator([]): You can also use the square bracket operator to add properties to an object. This way allows for dynamically setting property names. For example:<\/li>\n
  4. Create an object with two properties: ‘property1’ with the value ‘value1’ and ‘property2’ with the value ‘value2’.<\/li>\n
  5. Alternatively, you can use variables to set property names.<\/li>\n
  6. An empty object is created with the variable name “obj”. A property called “property1” is dynamically added to the object and assigned the value of “value1”.<\/li>\n
  7. By using the Object.defineProperty() method, you can define a new property on an object or modify an existing property. For example:<\/li>\n
  8. Create an empty object and define a property ‘property1’ with the value ‘value1’, allowing it to be modified, listed, and configured.<\/li>\n
  9. This method also allows for setting properties such as writability, enumerability, and configurability.<\/li>\n
  10. By using the Object.assign() method, you can copy one or more source object properties to a target object and return the target object. If the target object already has a property with the same name, the value of the property in the source object will override the value in the target object. For example:<\/li>\n
  11. Create an empty object called obj and then assign the properties property1 and property2 with values ‘value1’ and ‘value2’ to it.<\/li>\n
  12. This method allows you to add multiple attributes at the same time.<\/li>\n<\/ol>\n

    It is important to note that when using the above method to add properties to an object, if the object is a constant (declared using the const keyword), then new properties cannot be added to it. Only existing properties can be modified.<\/p>\n","protected":false},"excerpt":{"rendered":"
