Example

File : ex1.js

const _ = require('ccclodash')

console.log("_.chunk(['a', 'b', 'c', 'd'], 2)=", _.chunk(['a', 'b', 'c', 'd'], 2))
console.log("_.chunk(['a', 'b', 'c', 'd'], 3)=", _.chunk(['a', 'b', 'c', 'd'], 3))

Run

$ node ex1.js
_.chunk(['a', 'b', 'c', 'd'], 2)= [ [ 'a', 'b' ], [ 'c', 'd' ] ]
_.chunk(['a', 'b', 'c', 'd'], 3)= [ [ 'a', 'b', 'c' ], [ 'd' ] ]

File : ex2.js

const _ = require('ccclodash')

console.log("_.compact([0, 1, false, 2, '', 3])=", _.compact([0, 1, false, 2, '', 3]))

Run

$ node ex2.js
_.compact([0, 1, false, 2, '', 3])=[ 1, 2, 3 ]

File : ex3.js

const _ = require('ccclodash')

var array = [1]
console.log("_.concat(array, 2, [3], [[4]])=",  _.concat(array, 2, [3], [[4]]))

Run

$ node ex3.js
_.concat(array, 2, [3], [[4]])= [1, 2, [3], [[4]]]

Test

$ mocha

  chunk
    √ _.chunk(['a', 'b', 'c', 'd'], 2) equalTo [ [ 'a', 'b' ], [ 'c', 'd' ] ] (52ms)
    √ _.chunk(['a', 'b', 'c', 'd'], 3) equalTo [ [ 'a', 'b', 'c' ], [ 'd' ] ]
    √ _.chunk(['a', 'b', 'c', 'd'], 3) notEqualTo [ [ 'a', 'b'], ['c' , 'd' ] ]

  compact
    √ _.compact([0, 1, false, 2, '', 3]) equalTo [ 1, 2, 3 ]

  concat
    √ _.concat(array, 2, [3], [[4]]) equalTo [1, 2, [3], [[4]]] (73ms)
    √ _.concat(array, 2, [3], [[4]]) equalTo [ 1, 2, 3 ]
