1.0.2 • Public • Published


    Node package for creating an array which is indexed in the order of the Star Wars films.

    In other words, the indices for each array starts as follows:

    3 4 5 0 1 2 6 7 8 ...

    NOTE: This is an esoteric (joke) package. Although if you manage to actually use it in a meaningful way, I will be really impressed.



    $ npm i -s star-wars-array


    Usage is similar to a regular array.

    const SWArray = require("star-wars-array");
    let array = new SWArray([1, 2, 3, 4, 5, 6]);
    console.log(array[0]); // prints 4
    console.log(array[3]); // prints 1
    array.forEach((val, idx) => {
        console.log(`${idx} = ${val}`);
    /* prints:
        3 = 1
        4 = 2
        5 = 3
        0 = 4
        1 = 5
        2 = 6
    console.log(array.length); // prints 6

    Wait so how tf do I iterate?

    The easiest way to iterate over the array is to use the SWArray.keys() method as a lookup table to map the sequential indices of the loop to the correct indices for the array.

    let arr = new SWArray(...);
    let idx = arr.keys();
    for(let i = 0; i < arr.length; i++) {
        let val = arr[idx[i]];

    Alternatively, you can just convert it to a regular array and iterate over that instead, using either SWArray.toNormalArray() or SWArray.toOrderedArray().

    let arr = new SWArray(...);
    let iter = arr.toNormalArray();
    for(let i = 0; i < arr.length; i++) {
        let val = iter[i];


    The SWArray class implements some of the functions which are supported by native Javascript arrays, with the exception of all indices being in the format specified above.

    For shared functions, please see the documentation for the regular Javascript Array methods, since their arguments and return values are the same.

    Properties Type Usage
    length number See Array.prototype.length
    Method Return Type Usage
    push() number See Array.prototype.push
    pop() any or undefined See Array.prototype.pop
    forEach() undefined See Array.prototype.forEach
    indexOf() number See Array.prototype.indexOf
    includes() boolean See Array.prototype.includes
    toNormalArray() array Returns the values as a regular Javascript array with start-to-end ordering.
    toOrderedArray(boolean: removeGaps) array Returns the values as a regular Javascript array with SWArray ordering. If removeGaps is true, then any gaps left by the reordering are removed.
    toString() string See Array.prototype.toString
    keys() array See Array.prototype.keys
    map() SWArray See

    Planned Features

    • Implement remaining native array functions (full list here).
    • More prequel memes (which are surprisingly lacking).
    • Make it iterable so using it with loops are more pleasant.
