From this example, we can see that functions provide the following benefits: Reusable Code: Since functions are independent blocks of code, you can declare a function once and use it multiple times. For example, once you create a function to draw a circle, you can use it whenever you need...
Example varx =function(a, b) {return a * b}; Try it Yourself » After a function expression has been stored in a variable, the variable can be used as a function: Example varx =function(a, b) {return a * b}; varz = x(4,3); ...
Example constx =function(a, b) {returna * b}; letz = x(4,3); Try it Yourself » The function above is actually ananonymous function(a function without a name). Functions stored in variables do not need function names. They are always invoked (called) using the variable name. ...

In JavaScript you can define functions as object methods. The following example creates an object (myObject), with two properties (firstNameandlastName), and a method (fullName): Example constmyObject = { firstName:"John", lastName:"Doe", ...
Yes, you can use setInterval in Node.js. It works the same way as it does in the browser. Here’s an example: setInterval(() => { console.log('Hello, Node.js!'); }, 1000); In this code, ‘Hello, Node.js!’ will be logged to the console every second. ...
Convert a value to another type. Only applicable when conversions have been added withtyped.addConversion()and/ortyped.addConversions()(see below in the method list). Example: typed.addConversion({from:'number',to:'string',convert:function(x){return+x;}});varstr=typed.convert(2.3,'string'...
For every Fiori application we have Component.js, and there is a function extend() call. See one example below. What is the purpose of this function call and what functionality would it achieve? In order to understand the logic of extend, it is necessary to understand prototype concept in ...
