2,869 Points.split for two strings
hi, when I use the return statement to pass two strings into my first window.alert method, it seems to work alert//vicvi. However afterwards it says that split for name2 is undefined and breaks the rest of the code. I don't quite understand what is happening. Also how would you call two parameters from a function do you have to do a conditional statement?
Thank You
var myArray = [];
myArray = ["vic", "vic"];
var cutName = function(name, _name2) {
return name.split(", ") + _name2.split(', ');
}
window.alert(cutName("vic", "vi"));
window.alert(cutName( "yellow"));
var myInfo= {
fullName: cutName(myArray[0]),
favoriteColor: myArray[1],
github: myArray[2] || null
}
console.log(myInfo);

231,275 PointsThe function "cutName" is defined to take two arguments (name
and _name2
). So later in the code:
window.alert(cutName("vic", "vi")); // call has two arguments, no problem
window.alert(cutName( "yellow")); // call has only ONE argument!
Since the second call does not have a second argument, "_name2
" remains undefined and breaks the function.
The same thing happens here:
fullName: cutName(myArray[0]), // call has only ONE argument!
If you wanted to pass the array elements as separate arguments you could do this:
fullName: cutName(...myArray),
One last comment, it's not clear why you are using "split" here at all since none of the values contain the sequence it needs to work.
