When initializing the function call, the parameters are the function's arguments. Arguments are passed by value. The function knows only the values, not the argument's locations. If the function changes an argument's value, the parameter's original value is unchanged. A parameter is a type of data provided as input to the function. It is operated in the function that will be called/invoked. The Supported parameter types are string, integer, Boolean, and array. 


A function is a code block for performing a particular task in JavaScript. It is a reusable code that removes repetition. You can pass in any number of arguments when you call a function in JavaScript. There is no function parameter limit. We have two types of passing the value as parameters. 

  1. arguments object (ES5) 
  2. Rest parameters (ES6) 

Arguments object (ES5) 

Arguments are a local JavaScript object variable in Javascript. It is available in all non-arrow functions. This argument is an Array-like object. It is accessible inside functions. 

Rest Parameters (ES6) 

When working with an indefinite number of arguments, the rest parameter provides an easier way.  

The difference between rest arguments and the parameters object is as follows: 

  • We can filter all the array methods like map, sort, and filter directly on the rest parameters array, but not on the arguments object. It must first be converted to a real array to use Array methods on the arguments object. 
  • The rest parameter is a more informative syntax and is more straightforward of the function operation. 


Here is an example of how to perform Javascript Functions via 4 Parameters:

console.log(personalInfo);

Instructions

Follow the steps carefully to get the output easily.

  1. Download and Install VS Code on your Desktop.
  2. Open the VS Code and install Javascript ES6 Code Snippet and Code Runner from Extensions.
  3. Open the new file and save as filename.js
  4. Copy the code using the "Copy" button above, and paste it in your javascript file.
  5. Run the code using (ctr+alt+N) Run button.


I hope you found this useful. I have added version information in the following sections.


I found this code snippet by searching for ' Java script function via 4 parameters' in kandi. You can try any such use case!

Environment Tested

I tested this solution in the following versions. Be mindful of changes when working with other versions.

  1. The solution is created in VS Code 1.73.1 version.
  2. JavaScript (ES6) code snippets v1.8.0
  3. Code Runner v0.11.8


Using this solution, we are able to do Java script function via 4 parameters with simple steps. This process also facilities an easy way to use, hassle-free method to create a hands-on working version of code which would help us to do Java script function via 4 parameters.
