move-position

Move element in given array form index-A to index-B :scissors:

npm install move-position

move

/**
 * Moves element form/to index.
 *
 * @param {Array} [arr=[]]
 * @param {number} from
 * @param {number} to
 * @param {boolean} [isMutate=true]
 * @returns {Array}
 */
const modifiedArr = move(arr, from, to, isMutate);

Example(1)

const input = ["a", "b", "c"];

// move element form index=0, to index=2
const result = move(input, 0, 2);

// ["b", "c", "a"];

moveMultiArr

/**
 * Moves the same index in multiple arrays
 *
 * @param {Array} [arr=[]] Array contain arrays to be changed
 * @param {number} from - targeted index
 * @param {number} to - targeted index
 * @param {boolean} [isMutate=true]
 * @returns {Array}
 */
const modifiedArr = moveMultiArr([arr1, arr2, ...], from, to, isMutate);

Example(2)

const input1 = ["a1", "b1", "c1"];
const input2 = ["a2", "b2", "c2"];

const inputs = [input1, input2];

const result = moveMultiArr(inputs, 2, 0);

// result[0] > ["c1", "a1", "b1"];
// result[1] > ["c2", "a2", "b2"];

moveMultiIndex

/**
 * Moves multiple indexes in the same array
 *
 * @param {Array} [arr=[]]
 * @param {Object[]} movingMap
 * @returns {Array} new Array with index changes
 */
const modifiedArr = moveMultiIndex(arr, [{from, to}, ...]);

Example(3)

const input = ["a", "b", "c"];

const movingMap = [
  { from: 0, to: 2 },
  { from: 2, to: 1 }
];

const result = moveMultiIndex(input, movingMap);

// result > [ 'a', 'c', 'a' ]
