Implement a SortedMap in JavaScript.
JavaScript is one of the dynamic, cross-platform, and lightweight programming languages. The developer uses it for creating web pages and lots of non-browser surroundings. JavaScript implementations let the client-side development interact with the visitor and dynamic web page.
With JavaScript, you can develop network-centric apps. It involves core language elements, namely control structures, statements, operators, etc. The JavaScript object can serve as the map, and sorted maps are data structures. It expands the interface of the map and offers its entire elements ordering. Keep reading to know more about the sorted map implementation in JavaScript.
Sorted Map – What Does It Mean?
Sorted Map’s characteristics are ordering keys by a specified comparator or natural ordering.
Comparing that to JavaScript array sort(), you can see the difference.
- Lookup the object according to some keys
- Maintain things sorted order automatically
- Repeat throughout the item sorted list
- Object sets can shrink or develop dynamically
Implementing the AVL tree in JavaScript helps develop the sorted map on the active data set. Standard data collections don’t become available in the scripting language taken from dsjslib. In the dsjslib, the AVL tree sorts the map with log N entrance time for deleting, inserting, and finding operations.
Sorted Map Implementation
The followings are some tips on how to implement sorted map in JavaScript.
Some programmer uses objects to Map key to values in their JavaScript code.
var helloMap = {};
helloMap.de = “Hallo”;
helloMap[“en”] = “Hello”;
helloMap.es = “Hola”;
Remember that you cannot use some wrapper objects and hold arrays.
var HelloMap = function(){
this.myMap = [];
this.addProperty = function(key, value){
this.myMap.push({key: key, value: value});
}
}
You can use the empty object to maintain the property order, which adds to it. Let’s see coding:
var helloMap = {};
= helloMap = getOrderAwareObject(helloMap);
As a result, each assignment of procedure helloMap[“yz”] to “bar” and helloMap.xy to “foo” will track in the object “in order”.
Check Out Binary Search Trees.
Binary search trees are binary trees with different properties for every node. It is a robust data framework, and BST develops from various vital sequences.
The tree height stays small for a more extended period, you are excellent. The size of the binary search tree can vary based on the critical sequences placed in it. The programmer can insert, search and delete several elements in the BST.
AVL Tree
It makes them the balanced tree after every process. AVL Trees rotate the tree at particular nodes on deletion, addition, and maintaining lower height in the tree.
Sorted Map Interface Methods
Followings are some methods of sorted map that every developer should know:
- comparator()
- entrySet()
- last key()
- firstKey()
- headMap(K toKey)
- keyset()
- Values()
Popular JavaScript Development Tools
JavaScript does not need costly development tools for popular web page developers. The professional can start the process with a text editing tool like notepad. Different vendors use JavaScript development tools to make life hassle-free and straightforward. Let’s see a few JavaScript editing tools:
- Macromedia Dreamweaver MX
- Microsoft FrontPage
- Macromedia Homeset 5 and more
These tools are popular JavaScript editor that offers many inbuilt components that conform to modern standards and merge well with databases. You can select the right editor and complete the project promptly and bug-free according to your requirements.
