Age Range Compatibility Equation.js

/*
Description:
Everybody knows the classic "half your age plus seven" dating rule that a lot of people follow (including myself). It's the 'recommended' age range in which to date someone.



minimum age <= your age <= maximum age

#Task

Given an integer (1 <= n <= 100) representing a person's age, return their minimum and maximum age range.

This equation doesn't work when the age <= 14, so use this equation instead:

min = age - 0.10 * age
max = age + 0.10 * age
You should floor all your answers so that an integer is given instead of a float (which doesn't represent age). Return your answer in the form [min]-[max]

##Examples:

age = 27   =>   20-40
age = 5    =>   4-5
age = 17   =>   15-20
*/

function datingRange(age){
  return age>=14?`${Math.floor(age/2+7)}-${Math.floor((age-7)*2)}`:
                 `${Math.floor(age-(age*0.1))}-${Math.floor(age+(age*0.1))}`
}
