Combining a name using JavaScript even if certain parts are not available

How can I efficiently combine name elements without any extra white space in Vue.js?

let FirstName = "John"
let MI = "G"
let LastName = "Jones"
let Suffix = "Jr."

I want to create let fullName = "John G Jones Jr."

However, in cases like this:

let FirstName = "John"
let MI = "" or null
let LastName = "Jones"
let Suffix = "" or null

I aim for let fullName = "John Jones" without any additional white spaces.

Simply concatenating with spaces will not suffice. Is there a more elegant solution than using multiple if statements?

Considering the constraints of working within a Vue.js environment and not being able to rely on jQuery.

Thank you

Answer №1

To efficiently handle this situation, consider storing the values in an array and then filtering out any falsy values before joining them with a space delimiter.

let firstName = "John",
  middleInitial = "",
  lastName = "Jones",
  suffix = null,
  fullName = [firstName, middleInitial, lastName, suffix].filter(value => value).join(' ');

console.log(fullName)
