Instructions

Examples

maxNum(3, 7) // 7
maxNum(-1, 0) // 0
maxNum(1000, 400) // 1000

Notes

• READ EVERY WORD CAREFULLY, CHARACTER BY CHARACTER!
• Don’t overthink this challenge; it’s not supposed to be hard.

Solutions

// bugs
function maxNum(n1;n2) { // here,between paramters using `,` instead of `;`
	if (n1>n2) {
	  return n2 // here , we should return max number,n1
	}
  else if { // and here,remove `if`
	return n1
  }
}
// correct it !!
function maxNum(n1,n2) {
    if (n1>n2) {
        return n1
    } else  {
        return n1
    }
}

TestCases

let Test = (function(){
    return {
        assertEquals:function(actual,expected){
            if(actual !== expected){
                let errorMsg = `actual is ${actual},${expected} is expected`;
                throw new Error(errorMsg);
            }
        }
    }
})();

Test.assertEquals(maxNum(3, 7), 7)
Test.assertEquals(maxNum(-1, 0), 0)
Test.assertEquals(maxNum(1000, 400), 1000)
Test.assertEquals(maxNum(-3, -9), -3)
Test.assertEquals(maxNum(88, 90), 90)
