Entering the name of a global object instantiates it. Global objects provide entry points to server-side scripts.

Global objects and functions (JavaScript™).

Client-side scripts are interpreted by the browser.Ī simple action performs a pre-programmed activity that can be modified by arguments. The JavaScript described here applies to the server-side interpreter.

The JavaScript™ language elements are based on the ECMAScript Language Specification Standard ECMA-262 (see ). JavaScript™ language elements (JavaScript).

And you're equipped with a handy mnemonic, that splice compared to slice has an additional letter, 'p', which helps you remember that splice mutates and optionally adds or removes from the original array.This reference describes the JavaScript™ language elements, Application Programming Interfaces (APIs), and other artifacts that you need to create scripts, plus the XPages simple actions. You now know that slice makes a shallow copy of the original array, while splice mutates the original array and optionally adds or removes elements. ConclusionĪnd there we have it! This blog goes over the differences between slice and splice. And because splice can add and remove stuff to the original array, that means that it also mutates the original array. Because of the extra letter, I associate the additional letter to splice's use of adding or removing from the original array. splice has an extra letter, 'p', compared to slice. I remember the difference between slice and splice using a mnemonic. insert 'juliet' and 'zeke' at 3rd index // returns Ĭonsole. splice ( 3, 1, 'juliet', 'zeke' ) // remove 'harper'.
