Splitting an array using .split method javascript

Question

I apologize if this has been seen before but I am here:

var fullName = ["Linus Trovalds "];
var birthYear = [1969];
var myArray = [fullName + birthYear];
console.log(myArray);

And I am trying to declare a variable named splitName, and set it equal to fullName split into two separate objects in an array using the split method. In other words, splitName should equal ["Linus", "Torvalds"] when printed to the console. How should this be written so that split name is printed to the console as mentioned above?

This split method is not working for me.

Any help will be greatly appreciated.

• miir: .split(delimeter) is a method for Strings. In your code, the variable fullName is an Array object because you define it with square brackets [ ]. The first and only element within your fullName array is a string: so var nameString = fullName[0] will give you back the name as a string. Then you can do var firstLastArray = nameString.split(' '); to split on the space. Or you could just define var fullName = "Linus Trovalds "; as a string instead of an array.
• nnnnnn: How does the birthYear fit into what you're asking about splitting the value of the name?
• forJ: @nnnnnn It probably doesn't. But I used to make same mistakes too.
• str8up7od: @nnnnnn it doesn't at this point but I figured it out. var fullName = 'Linus Trovalds'; var splitName = fullName.split(' ', 2); console.log(splitName)
• str8up7od: now I am trying to write a function that when called prints out a string with the where the 1st index value from splitName array is printed. I think I am supposed to use .shift I tried this but no luck: function sayHello();{ var splitName = "Linus", "Trovalds"; var firstName = splitName.shift(1); return "Hello, " + firstName + "!"; I keep getting a syntax error, any clue why?

I don't know how you have tried it but on top of my head I think you might have forgotten that fullName variable is an array.

Try console.log(fullName[0].split(" "));

• str8up7od: I figured it out. var fullName = 'Linus Trovalds'; var splitName = fullName.split(' ', 2); console.log(splitName)
• str8up7od: now I am trying to write a function that when called prints out a string with the where the 1st index value from splitName array is printed. I think I am supposed to use .shift I tried this but no luck: function sayHello();{ var splitName = "Linus", "Trovalds"; var firstName = splitName.shift(1); return "Hello, " + firstName + "!"; I keep getting a syntax error, any clue why?
• forJ: @str8up7od splitName[0] will give you the first index value. You should read more about arrays

Or you could have simply split the fullName variable at the [5] mark to separate it into two strings in an array:

So it would be (for those looking for this in the future),

var fullName = ["Linus Trovalds"];
var birthYear = [1969];
var myArray = [fullName + birthYear];
var splitName = fullName.split(fullName[5])
//which would output ["Linus", "Trivolds"];
console.log(splitName)
//I changed this since I'm assuming you want the output to be the new array
