JavaScriptUtil

Working with arrays

There are several functions to perform operations on arrays.

The best place to look at the JavaScriptUtil API documentation, that have a complete list of functions. Here, the idea is not to replicate that information, but to give a basic understanding.

The indexOf, inArray and arrayEquals functions tests elements and arrays;

var letters = ["a", "b", "c", "d"];
indexOf("b") -> 1
indexOf("x") -> -1
inArray("b", letters) -> true
arrayEquals(letters, ["a", "b"]) -> false
arrayEquals(letters, ["a", "b", "c", "d"]) -> true

The arrayConcat and removeFromArray functions return new arrays based on other arrays, by adding and removing elements.

var letters = ["a", "b", "c", "d"];
arrayConcat(letters, "e", ["f", "g"]) -> ["a", "b", "c", "d", "e", "f", "g"]
removeFromArray(letters, "b") -> ["a", "c", "d"]
removeFromArray(letters, "a", "c") -> ["b", "d"]
