Move element in a given array from one index to another ..with some extrafunctions.

npm install move-position

API

move

Moves element form one index to another with ability to fill each position andmutate the input array.

functionmove<T>(  arr: T[] = [],  movingMap: ArrayRange | ArrayRange[],  Opts<T> ={})

  • ArrayRange object contains:

    • from: number - Target index.
    • to: number - Destination index.

  • Opts object contains:

    • isMutate?: boolean - Defaulttrue - Mutate array input or create new one.
    • isDuplicate?: boolean - Defaultfalse - Duplicate the traveled element or not.
    • isSwap?: boolean - Defaultfalse - Swap between array elements.
    • fill?: T - Fill the original position with a value.

Example -move

Trying default options:

constINPUT=["first","second","third","fourth"];constmovingMap=[{from:0,to:3}];constresult=move(INPUT,movingMap);>>result=["fourth","second","third","first"];

EnablesisDuplicate:true:

constINPUT=["first","second","third","fourth"];constmovingMap=[{from:0,to:3}];constresult=move(INPUT,movingMap,{isDuplicate:true});//>>result=["first","second","third","first"];

With nullish:

constINPUT=["first","second","third","fourth"];constmovingMap=[{from:0,to:3}];constresult=move(INPUT,movingMap,{isDuplicate:false,isSwap:false,});>>result=[null,"second","third","first"];

With custom fill:

constINPUT=["first","second","third","fourth"];constmovingMap=[{from:0,to:3}];constresult=move(INPUT,movingMap,{fill:"emptiness"});>>result=["emptiness","second","third","first"];

compare

Compare elements of the first array with the rest of arrays.

functioncompare<T>(...args: T[][])

Example -compare

constdiff=compare(["a","b","c"],["b","c","e"]);>diff=["a"]

compareBoth

Compare elements in all inputs and gets the difference.

functioncompareBoth<T>(...args: T[][])

Example -compareBoth

constallDiff=compareBoth(["a","b","c"],["b","c","e"]);>allDiff=["a","e"]

flatten

Flatten an array

functionflatten<T>(unFlatten: T[])

Example -flatten

constflattened=flatten([[1,[2,3]],[1,[2,3]],0]);>flattened=[1,2,3,1,2,3,0]

toArray

Convert an input to array

functionflatten<T>(unFlatten: T[])

Example -toArray

constarray=toArray("a");>array=["a"]

Tests

npmtest
