Given input string representing time in military format, return the standard time equivalent
Example:
toStandardTime('13:22') should return '01:22 pm' var line = '****************************************************************'; var passed = 0;/* w ww . ja v a 2 s.c o m*/ var failed = 0; console.log(line); console.log('toStandardTime UNIT TESTS'); console.log(line); if ( toStandardTime('03:16') === '03:16 am') { console.log("Test 1 pass, toStandardTime('03:16') returns '03:16 am'"); passed += 1; } else { console.log("Test 1 failed, toStandardTime('03:16') should return '03:16 am'"); failed += 1; } if ( toStandardTime('13:22') === '01:22 pm') { console.log("Test 2 pass, toStandardTime('13:22') returns '01:22 pm'"); passed += 1; } else { console.log("Test 2 failed, toStandardTime('13:22') should return '01:22 pm'"); failed += 1; } console.log(line); console.log('TOTAL TESTS PASSED: ' + passed ); console.log('TOTAL TESTS FAILED: ' + failed ); console.log(line);
function toStandardTime(militaryTime) { var hour = Number(militaryTime.slice(0, 2)); var minute = militaryTime.slice(3); var extension = 'am'; if (hour > 12) { hour -= 12; extension = 'pm'; } else if (hour === 0) { hour = 12; } var standardTime = displayDoubleDigit(hour) + ':' + minute + ' ' + extension; return standardTime; } var line = '****************************************************************'; var passed = 0; var failed = 0; console.log(line); console.log('toStandardTime UNIT TESTS'); console.log(line); if ( toStandardTime('03:16') === '03:16 am') { console.log("Test 1 pass, toStandardTime('03:16') returns '03:16 am'"); passed += 1; } else { console.log("Test 1 failed, toStandardTime('03:16') should return '03:16 am'"); failed += 1; } if ( toStandardTime('13:22') === '01:22 pm') { console.log("Test 2 pass, toStandardTime('13:22') returns '01:22 pm'"); passed += 1; } else { console.log("Test 2 failed, toStandardTime('13:22') should return '01:22 pm'"); failed += 1; } console.log(line); console.log('TOTAL TESTS PASSED: ' + passed ); console.log('TOTAL TESTS FAILED: ' + failed ); console.log(line);
