Move element in given array form index-A to index-B
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' ]
