`js`
function move
arr: T[] = [],
movingMap: ArrayRange | ArrayRange[],
Opts
)
- ArrayRange object contains:
- from: number - Target index.to: number
- - Destination index.
- Opts object contains:
- isMutate?: boolean - Default true - Mutate array input or create new one.isDuplicate?: boolean
- - Default false - Duplicate the traveled element or not.isSwap?: boolean
- - Default false - Swap between array elements.fill?: T
- - Fill the original position with a value.
Trying default options:
`js
const INPUT = ["first", "second", "third", "fourth"];
const movingMap = [{ from: 0, to: 3 }];
const result = move(INPUT, movingMap);
>> result= ["fourth", "second", "third", "first"];
`
Enables isDuplicate:true:
`js
const INPUT = ["first", "second", "third", "fourth"];
const movingMap = [{ from: 0, to: 3 }];
const result = move(INPUT, movingMap, { isDuplicate: true });
//
>> result= ["first", "second", "third", "first"];
`
With nullish:
`js
const INPUT = ["first", "second", "third", "fourth"];
const movingMap = [{ from: 0, to: 3 }];
const result = move(INPUT, movingMap, {
isDuplicate: false,
isSwap: false,
});
>> result = [null, "second", "third", "first"];
`
With custom fill:
`js
const INPUT = ["first", "second", "third", "fourth"];
const movingMap = [{ from: 0, to: 3 }];
const result = move(INPUT, movingMap, {
fill: "emptiness"
});
>> result = ["emptiness", "second", "third", "first"];
`
> Compare elements of the first array with the rest of arrays.
`js`
function compare
`js
const diff = compare(["a", "b", "c"], ["b", "c", "e"]);
> diff = ["a"]
`
> Compare elements in all inputs and gets the difference.
`js`
function compareBoth
`js
const allDiff = compareBoth(["a", "b", "c"], ["b", "c", "e"]);
> allDiff = ["a", "e"]
`
> Flatten an array
`js`
function flatten
`js
const flattened = flatten([[1, [2, 3]], [1, [2, 3]], 0]);
> flattened = [1, 2, 3, 1, 2, 3, 0]
`
> Convert an input to array
`js`
function flatten
`js
const array = toArray("a");
> array = ["a"]
