There is code:
function Hours(days){
weekHours = 0;
for(i = 0; i != days.length; i++){
if(days[i].length > 3){
dayHours = days[i].trim().split('-');
weekHours += parseFloat(dayHours[1]) - parseFloat(dayHours[0]);
}
}
return weekHours;
}
var fruits = [" 8-16 ", " 8-23 ", " 17-23 ", " 16-23 ", " 8-16 ", " 12-18 ", " В "];
console.log(Hours(fruits));Why i have this errors:
TypeError: Cannot read property 'length' of undefined
TypeError: days[i].trim is not a function
TypeError: days[i].strip is not a function
It's acting as if an undefined or null is in your fruits array. Did you have an extra comma in it originally, because the code works fine as-is.
Meaning,
var fruits = ['8-16',' B ']; is fine but
var fruits = ['8-16',,' B ']; is not.
