JS Split Property

Navigation
0

I'm doing some tests with arrays and functions, in case I want the program to look up a name that is in the names array. The routine even works, but the console has an error in the Slip and if the value of the String name is not found, it can not display the console.log at the end.

The error that appears and this: "Error: TypeError: Unable to get property 'split' of undefined or null reference"

You are trying to access a position of the "names" array that does not exist, so it is not possible to do split .

Change the repeat loops by removing the equal sign = 

 for (var i = 0; i < nomes.length; i++) {...}
