Instructions

Create a function that accepts a measurement value in inches and returns the equivalent of the measurement value in feet.

Examples

javascript">inchesToFeet(324) // 27
inchesToFeet(12) // 1
inchesToFeet(36) // 3

Notes

• If inches are under 12, return 0.
• 12 inches = 1 foot.

Solutions

javascript">function inchesToFeet(inches) {
	return Math.floor(inches/12)
}

TestCases

javascript">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(inchesToFeet(12), 1)
Test.assertEquals(inchesToFeet(360), 30)
Test.assertEquals(inchesToFeet(3612), 301)
Test.assertEquals(inchesToFeet(324), 27)
Test.assertEquals(inchesToFeet(3012), 251)
Test.assertEquals(inchesToFeet(11), 0)
