How to join two strings in JavaScript
Find out how to combine strings using JavaScript
JavaScript, like any good language, has the ability to join 2 (or more, of course) strings.
How?
We can use the +
operator.
If you have a string name
and a string surname
, you can assign those too the fullname
variable like this:
const fullname = name + surname
If you don’t want to instantiate a new variable, you can use the +=
operator to add the second string to the first:
name += surname
Alternatively you can also use the concat()
method of the String object, which returns a new string concatenating the one you call this method on, with the argument of the method:
const fullname = name.concat(surname)
I generally recommend the simplest route (which also happen to be the faster) which is using the +
(or +=
) operator.
