In the following example we are going to learn how to set dynamic property keys to an object in JavaScript. To add dynamic property keys to an object in JavaScript, there are three possible ways. There are three possible ways to set dynamic property keys to an object. The first possible way is to create a key and assign it to the object, second possible way is to set the dynamic property keys to an object using the define property method and the third possible way is to set the dynamic property keys to an object using ES6 method. We ... Read More

In this article we are going to discuss how to access an object value using variable key in JavaScript. An object value can be accessed by a Dot Notation and a Bracket Notation. To get the object value through a variable key, the value or expression inside the bracket notation must match with the existing key name, then it returns a value. The bracket notation, unlike the dot notation can be used with variables. If we are using a variable with bracket notation, the variable must reference a string. Let’s understand this concept better with the help of examples further ... Read More

In this article we are going to discuss how to convert a value into Boolean in JavaScript. In JavaScript programming we sometimes need values like these ‘YES / NO, ‘ON / OFF’, ‘TRUE / FALSE’. So, JavaScript provides Boolean() method, which helps us to convert a value into Boolean. A Boolean is a value that can return either true/false. There are two ways using which we can convert values into Boolean. One way is to use Boolean() method and the other way is to use the !! notation. Let’s understand this concept better with the help of the examples further ... Read More

In this article we are going to learn how to find the action attribute and method of a form with suitable examples in JavaScript. In HTML, there is  elements which has few attributes: input, label, text area, select, name, target. The action and method attributes of the form are used to return those values. The action attribute also specifies where to send the form data when form is submitted. To get a better idea of this concept, let’s look into JavaScript examples where we achieved the given task using action attribute and also with method attribute. Using action ... Read More
