JavaScript Property
In JavaScript, a property is a characteristic or attribute of an object. It is a key-value pair, where the key (also known as the property name) is a string and the value can be of any data type (such as a number, string, or another object). Properties can be accessed and modified using the dot notation (e.g. object.property) or the bracket notation (e.g. object[‘property’]).
JavaScript Object
A JavaScript object is a collection of properties, which are represented as key-value pairs. Objects are used to store and manipulate data, and can be used to model real-world objects or abstract concepts. Objects can be created using object literals, which are enclosed in curly braces ({}), or by using the object constructor or the object initializer syntax. Once created, properties can be added, modified, or deleted from an object, and the values of the properties can be accessed using the dot notation (e.g. object.property) or the bracket notation (e.g. object[‘property’]). Objects can also have methods, which are functions that are properties of an object. Objects can also be created using class constructor.
Remove regex property from JavaScript Object
In JavaScript, you can remove a property from an object using the ‘delete’ operator. For example, if you have an object ‘obj’ and you want to remove a property ‘prop’, you can use the following code:
delete obj.prop;Alternatively, you can also use the ‘Object.defineProperty()’ method with the ‘configurable’ property set to ‘false’, but this method is not widely supported.
Object.defineProperty(obj, "prop", {
configurable: false
});You also can use a ‘Object.assign’ or ‘spread operator’ (ES6) to create a new object without the property you want to delete
const { prop, ...rest } = obj;This will remove the ‘prop’ property from the object and rest will have the remaining properties.
