js-zip

Implement zip function of python, used to transform a matrix,such as:

[
    [1,2,3],
    [4,5,6],
    [7,8,9]
]

to:

[
    [1,4,7],
    [2,5,8],
    [3,6,9]
]

Each row must be iteratable object,such as Array,String

Installation

npm i -S js-zip

Example

• Multi Arrays

const JsZip = require('js-zip');
const a = [1,2,3];
const b = [4,5,6];
const c = [7,8,9];
const matrix = JsZip(a, b, c);

output matrix is:

[
    [1,4,7],
    [2,5,8],
    [3,6,9]
]

• Matrix

const JsZip = require('js-zip');
const arr = [[1,2,3], [4,5,6], [7,8,9]];
const matrix = JsZip(...arr);

output matrix is:

[
    [1,4,7],
    [2,5,8],
    [3,6,9]
]

• String List

const JsZip = require('js-zip');
const arr = ['abc', 'def', 'xyz'];
const maxtrix = JsZip(...arr);

output matrix is:

 [ 
     [ 'a', 'd', 'x' ], 
     [ 'b', 'e', 'y' ], 
     [ 'c', 'f', 'z' ] 
 ]
