Example Analysis of using objects instead of argument lists for function parameters in JavaScript

This article shares with you the content of an example analysis of using objects instead of parameter lists for function arguments in JavaScript. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Function arguments use objects instead of argument lists

When we use the parameter list to pass parameters to the function, it will be troublesome if there are fewer parameters or more parameters, because we have to pass the parameters in the order of the parameter list. If you use TypeScript to write, you also need to put optional parameters after required parameters when writing.

If we have more parameters of the function, we can consider passing parameters in the form of an object. When passing parameters in the form of an object, passing optional parameters does not need to be placed at the end, and the order of the parameters is not important. Compared with the parameter list, the content passed through the object is also easier to read and understand.

Let's look at an example:

Function getItem (price, quantity, name, description) {} getItem (15, undefined, 'bananas',' fruit')

Let's use the object to pass parameters:

Function getItem (args) {const {price, quantity, name, description} = args} getItem ({name: 'bananas', price: 10, quantity: 1, description:' fruit'}) Thank you for reading!
