Qaxt

The modern JavaScript module that makes writing code quciker and easier! Qaxt is aimed to be more lightweight and useful than my original project Quxt

Installation

npm install qaxt

yarn add qaxt

Quick Start

Here is a quick template to get started!

CJS

const _ = require('qaxt')

ESM

import _ from 'qaxt'

Example

Here is a small snippet to test the module!

var result = null

for (let i of _.range(0, 10, 2)) {
  console.log(i)
}

for (let i of _.range(10, 0)) {
  console.log(i)
}

const users = [
  {
    name: 'foo',
    age: 8,
    deleted: false,
  },
  {
    name: 'bar',
    age: 18,
    deleted: false,
  },
  {
    name: 'baz',
    age: 13,
    deleted: true,
  },
  {
    name: 'qux',
    age: 13,
    deleted: false,
  },
]

// Gets objects with the same key & value pairs
result = users.filter(_.matches({ name: 'foo' }))
console.log(result)

// Gets objects where a key is equal to a value
result = users.filter(_.matchesProperty(['age', 13]))
console.log(result)

// Gets objects with truthy deleted values
result = users.filter(_.property('deleted'))
console.log(result)

// Gets objects with key & value pairs with an expression
result = users.filter(_.must({ age: `>= 13` }))
console.log(result) // 13+ year olds

// Like before but takes multiple expressions
result = users.filter(_.must({ age: ['||', '=== 18', '=== 8'] }))
console.log(result) // must be 18 or 8 years old

/* Returns list of [0] matched values [1] other values */

// Partition with function rule
result = _.partition(users, _.must({ name: `[0] === 'b'` }))
console.log(result) 

// The matches() shorthand
result = _.partition(users, { age: 13 })
console.log(result)

// The matchesProperty() shorthand
result = _.partition(users, ['name', 'qux'])
console.log(result)

// The property() shorthand
result = _.partition(users, 'deleted')
console.log(result)

/* OR, NOT, AND, XOR operations on arrays */

const one = ['foo', 'bar', 'baz']
const two = ['bar', 'baz']
const three = ['baz', 'qux']

// Unites multiple arrays
result = _.unite(one, two, three)
console.log(result)

// Subtracts an array from another
result = _.subtract(one, two, three)
console.log(result)

// Returns the common elements in arrays
result = _.intersect(one, two, three)
console.log(result)

// Gets the symmetric difference
result = _.exclude(one, two, three)
console.log(result)

/* Stastics and Data */

const companies = ['google', 'amazon', 'microsoft', 'google', 'apple', 'amazon', 'netflix']

result = _.frequency(companies)
console.log(result)

result = _.mode(companies)
console.log(result)

/* Maths */

// Returns true if the number is prime
console.log(_.prime(7))

// Gets the highest common factor of multiple integers
console.log(_.hcf(24, 51, 18))

// Same as hcf() but only takes 2 integers recursively
console.log(_.gcd(138, 207))

// Gets the factors of a number in pairs
console.log(_.factors(144))

// Sorting
result = _.quickSort(_.factors(144))
console.log(result)

result = _.shellSort(_.factors(128))
console.log(result)

/* Array Management */

// Zip
result = _.zip(['username', 'pasword'], ['foo', 'bar'], ['baz', 'qux'])
console.log(result)

Major Updates

• Added intersectBy and excludeBy
• Added simul for iterating multiple lists
• Added equal that works for lists and objects
