We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.

The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.

When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.

To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!

Singly linked list.

## Installation ```bash npm install @stdlib/utils-linked-list ``` Alternatively, - To load the package in a website via a `script` tag without installation and bundlers, use the [ES Module][es-module] available on the [`esm`][esm-url] branch (see [README][esm-readme]). - If you are using Deno, visit the [`deno`][deno-url] branch (see [README][deno-readme] for usage intructions). - For use in Observable, or in browser/node environments, use the [Universal Module Definition (UMD)][umd] build available on the [`umd`][umd-url] branch (see [README][umd-readme]). The [branches.md][branches-url] file summarizes the available branches and displays a diagram illustrating their relationships. To view installation and usage instructions specific to each branch build, be sure to explicitly navigate to the respective README files on each branch, as linked to above.

## Usage ```javascript var linkedList = require( '@stdlib/utils-linked-list' ); ``` #### linkedList() Returns a new linked list instance. ```javascript var list = linkedList(); // returns ``` ##### list.clear() Clears a list. ```javascript var list = linkedList(); // returns // Add values to the list: list.push( 'foo' ).push( 'bar' ); // Peek at the first value: var v = list.first().value; // returns 'foo' // Examine the list length: var len = list.length; // returns 2 // Clear all list items: list.clear(); // Peek at the first value: v = list.first(); // returns undefined // Examine the list length: len = list.length; // returns 0 ``` ##### list.first() Returns the first `node`. If the list is currently empty, the returned value is `undefined`. ```javascript var list = linkedList(); // returns // Add values to the list: list.push( 'foo' ).push( 'bar' ); // Peek at the first value: var v = list.first().value; // returns 'foo' ``` ##### list.insert( node, value ) Inserts a `value` into the list **after** a provided list `node`. ```javascript var list = linkedList(); // returns // Add values to the list: list.push( 'foo' ).push( 'bar' ).push( 'beep' ); // Determine the list length: var len = list.length; // returns 3 // Get the second node: var node = list.first().next; // Insert a value after the second node: list.insert( node, 'boop' ); // Determine the list length: len = list.length; // returns 4 ``` ##### list.iterator() Returns an iterator for iterating over a list. If an environment supports `Symbol.iterator`, the returned iterator is iterable. ```javascript var list = linkedList(); // Add values to the list: list.push( 'foo' ).push( 'bar' ); // Create an iterator: var it = list.iterator(); // Iterate over the list... var v = it.next().value; // returns 'foo' v = it.next().value; // returns 'bar' var bool = it.next().done; // returns true ``` **Note**: in order to prevent confusion arising from list mutation during iteration, a returned iterator **always** iterates over a list "snapshot", which is defined as the list of list elements at the time of `list.iterator()` invocation. ##### list.last() Returns the last `node`. If the list is currently empty, the returned value is `undefined`. ```javascript var list = linkedList(); // returns // Add values to the list: list.push( 'foo' ).push( 'bar' ); // Peek at the last value: var v = list.last().value; // returns 'bar' ``` ##### list.length List length. ```javascript var list = linkedList(); // Examine the initial list length: var len = list.length; // returns 0 // Add values to the list: list.push( 'foo' ).push( 'bar' ); // Retrieve the current list length: len = list.length; // returns 2 ``` ##### list.pop() Removes a value from the end of the list. If the list is currently empty, the returned value is `undefined`. ```javascript var list = linkedList(); // Add values to the list: list.push( 'foo' ).push( 'bar' ); // Remove the last value: var v = list.pop(); // returns 'bar' // Add a new value to the list: list.push( 'beep' ); // Remove the last value: v = list.pop(); // returns 'beep' ``` ##### list.push( value ) Adds a value to the end of the list. ```javascript var list = linkedList(); // Add values to the list: list.push( 'foo' ).push( 'bar' ); // Remove the last value: var v = list.pop(); // returns 'bar' // Add a new value to the list: list.push( 'beep' ); // Remove the last value: v = list.pop(); // returns 'beep' ``` ##### list.remove( node ) Removes a `node` from the list. ```javascript var list = linkedList(); // Add values to the list: list.push( 'foo' ).push( 'bar' ).push( 'beep' ); // Determine the list length: var len = list.length; // returns 3 // Get the second node: var node = list.first().next; // Remove the second node: var v = list.remove( node ); // returns 'bar' // Determine the list length: len = list.length; // returns 2 ``` ##### list.shift() Removes a value from the beginning of the list. If the list is currently empty, the returned value is `undefined`. ```javascript var list = linkedList(); // Add values to the list: list.push( 'foo' ).push( 'bar' ); // Remove the first value: var v = list.shift(); // returns 'foo' // Add a new value to the list: list.push( 'beep' ); // Remove the first value: v = list.shift(); // returns 'bar' ``` ##### list.toArray() Returns an array of list values. ```javascript var list = linkedList(); // Add values to the list: list.push( 'foo' ).push( 'bar' ); // Get an array of list values: var vals = list.toArray(); // returns [ 'foo', 'bar' ] ``` ##### list.toJSON() Serializes a list as JSON. ```javascript var list = linkedList(); // Add values to the list: list.push( 'foo' ).push( 'bar' ); // Serialize to JSON: var o = list.toJSON(); // returns { 'type': 'linked-list', 'data': [ 'foo', 'bar' ] } ``` **Note**: `JSON.stringify()` implicitly calls this method when stringifying a list instance. ##### list.unshift( value ) Adds a value to the beginning of the list. ```javascript var list = linkedList(); // Add values to the list: list.unshift( 'foo' ).unshift( 'bar' ); // Remove the last value: var v = list.pop(); // returns 'foo' // Add a new value to the list: list.unshift( 'beep' ); // Remove the last value: v = list.pop(); // returns 'bar' ```

## Examples ```javascript var linkedList = require( '@stdlib/utils-linked-list' ); // Create a new linked list: var list = linkedList(); // Add some values to the list: list.push( 'foo' ); list.push( 'bar' ); list.push( 'beep' ); list.push( 'boop' ); // Peek at the first and last list values: var v = list.first().value; // returns 'foo' v = list.last().value; // returns 'boop' // Inspect the list length: var len = list.length; // returns 4 // Remove the last list value: v = list.pop(); // returns 'boop' // Inspect the list length: len = list.length; // returns 3 // Iterate over the list: var iter = list.iterator(); var i; for ( i = 0; i < len; i++ ) { console.log( 'List value #%d: %s', i+1, iter.next().value ); } // Clear the list: list.clear(); // Inspect the list length: len = list.length; // returns 0 ```
