However, for the second scenario, we are passing only one param, so the function will consider it the first value of the Parameter. The function checks blogType variable is undefined or not. In this scenario type value will be" DefaultType". Using arguments variable JavaScript functions have ...
To define an optional parameter in a JavaScript function, you simply assign a default value to the parameter in the function definition. For example: jsx function greet(name = "user") { console.log(`Welcome to GoLinuxCloud, ${name}! Here we have fun and learn`); } In this example,...
I have attached an image of an example. The Form.getElements function requires only 1 parameter, but has 2 optional parameters. In the JavaDoc statement for the function I state which arguments are optional and would like to a) know if there is a way...

If you do not care about its type, but just want it to have a default value, you should type your parameter asundefined example: arguments=__({name:[undefined,'unknown']}); Utilities Some JavaScript methodsdo not work intuitivelywhen dealing with types. This is why we made available these...

Thera are different ways to make a parameter optional. Using Default Value Example Live Demo using System; namespace DemoApplication{ class...

While using a single signature preserves the parameter names in the type information (as you can see in earlier examples), providing multiple signatures can obscure them. This does not affect the runtime behavior of functions, but it can make the type information less readable. Despite these ...
