I have defined my JavaScript function as follows:<\/p>\n

function printCompanyName(company1, company2, company3, company4, company5)\n{\ndocument.write(\"
\" + company1 + \"

\");\ndocument.write(\"
\" + company2 + \"

\");\ndocument.write(\"
\" + company3 + \"

\");\ndocument.write(\"
\" + company4 + \"

\");\ndocument.write(\"
\" + company5 + \"

\");\n}\n<\/code><\/pre>\n
And called it as follows:<\/p>\n
printCompanyName(\"Dell, Microsoft, Apple, Gizmodo, Amazon\");\n<\/code><\/pre>\n
But I get the following output:<\/p>\n
Dell, Microsoft, Apple, Gizmodo, Amazon\n\nundefined\n\nundefined\n\nundefined\n\nundefined\n<\/code><\/pre>\n
What gives!? I have been trying to figure this out for hrs. I want:<\/p>\n
Dell\nMicrosoft\nApple\nGizmodo\nAmazon\n<\/code><\/pre>\n
    \n
  1. \n
    You want to call:<\/p>\n
    printCompanyName(\"Dell\", \"Microsoft\", \"Apple\", \"Gizmodo\", \"Amazon\");\n<\/code><\/pre>\n
    The way you’re currently doing it you’re passing in one company “Dell, Microsoft, Apple, Gizmodo, Amazon”.<\/p>\n<\/li>\n
  2. \n
    You’re passing a single string that happens to contain 4 commas. Therefore, the first parameter contains that single string, and the other 4 are undefined. (Sisnce you only gave one value)<\/p>\n
    Since Javascript parameters are optional, you don’t get an error by not passing values for the other parameters.<\/p>\n
    You need to pass 5 different strings with commas between them, like this:<\/p>\n
    printCompanyName(\"Dell\", \"Microsoft\", \"Apple\", \"Gizmodo\", \"Amazon\");\n<\/code><\/pre>\n<\/li>\n
  3. \n
    Try this:<\/p>\n
    printCompanyName(\"Dell\", \"Microsoft\", \"Apple\", \"Gizmodo\", \"Amazon\");\n<\/code><\/pre>\n<\/li>\n<\/ol>\n
