I am trying to join a single string Blake Price together, so remove the space " " in between the first and last name (BlakePrice). Are you even able to join a single string in an array?

function openprofile(user) {
  console.log(user)
  var userarray = [user]
  var usernamejoined = userarray.join('')
  console.log(usernamejoined)
}

• javascript
• arrays
• string

• 1 Yes, you can use the join function to bine multiple items in an array into a single string using your specified delimiter (''). But if your variable userarray only contains one item, it will not work. You can instead use replace to remove the space from a single string: user.replace(" ", "");. – George Sun Commented Sep 23, 2021 at 1:29

You can split the username with space and you will get an array of each word like this ['Blake', 'Price']. And you join all strings in an array with an empty string and you will get "BlakePrice"

The code is like this

const username = "Blake Price"
const joinedUsername = username.split(' ').join('')
console.log(joinedUsername)

I believe what you are looking for is function 'split' instead of join. Example:

function openfile(user) {
    // also add try-catch block
    console.log(usersplit)
    var usersplit = user.split(" ")
    console.log(usersplit[0] + usersplit[1])
}

Now:

openfile("Blake Price")

Prints out "BlakePrice".

You can use .split(" ") to cut each word with a space and put it in an array for example :

var user = 'black price'
console.log(user.split(' '))

result[('black', 'price')]

And use .join('') to concatenate an entire array into a string without any spaces. And this example code for your case:

var openprofile = (username) => {
  var usernamejoined = username.split(' ').join('')
  return usernamejoined
}

console.log(openprofile('black price'))   // output:- blackprice
