Usage

With numbers:

const between = require('in-between')
 
const between1and10 = between(1, 10)
 
between1and10(10) //=> false
 
between1and10(3) //=> true
 
betweenAandZ('*') //=> throws error
 
between1and10(1) //=> false
 
between(100, 200)(101) //=> true
 

Works with alphabet characters:

 
const between = require('in-between')
 
const betweenAandD = between('a', 'd')
 
betweenAandD('b') //=> true
 
betweenAandD('z') //=> false
 

Works with Dates as well:

 
const between = require('in-between')
 
let myGraduation = new Date("October 13, 2014 11:13:00")
 
let myFirstJob =  new Date("September 1, 2015 11:13:00")
 
let myBirthDay =  new Date("January 10, 2015 10:11:03")
 
between(myGraduation, myFirstJob)(myBirthDay) //=> true
 

You can include the boundaries:

 
const between = require('in-between')
 
between(3, 4, true)(3) //=> true
 
between('a', 'b', true)('a') // => true
