Instructions

A bartender is writing a simple program to determine whether he should serve drinks to someone. He only serves drinks to people 18 and older and when he’s not on break.

Given the person’s age, and whether break time is in session, create a function which returns whether he should serve drinks.

Examples

shouldServeDrinks(17, true) // false
shouldServeDrinks(19, false) // true
shouldServeDrinks(30, true) // false

Notes

• Return true or false.
• Some countries have a slightly higher drinking age, but for the purposes of this challenge, it will be 18.

Solutions

function shouldServeDrinks(age, onBreak) {return age>=18 && !onBreak
}

TestCases

let Test = (function(){return {assertEquals:function(actual,expected){if(actual !== expected){let errorMsg = `actual is ${actual},${expected} is expected`;throw new Error(errorMsg);}},assertSimilar:function(actual,expected){if(actual.length != expected.length){throw new Error(`length is not equals, ${actual},${expected}`);}for(let a of actual){if(!expected.includes(a)){throw new Error(`missing ${a}`);}}}}
})();Test.assertEquals(shouldServeDrinks(17, true), false)
Test.assertEquals(shouldServeDrinks(30, true), false)
Test.assertEquals(shouldServeDrinks(24, false), true)
Test.assertEquals(shouldServeDrinks(18, false), true)
Test.assertEquals(shouldServeDrinks(3, false), false)
