Combine Two Strings with Concat() in Node.js

How do you use concat() method to combine two strings in Node.js?

The concat() method concatenates a string argument to the calling string and returns a new string.

In the examples below, we will take two strings and combine them using the concat() method.

Here's the full code:

const str1 = "Taco"
const str2 = "Bell"

const newString = str1.concat(str2)
// newString = "TacoBell"

And we can add a space between the two words with either of the two methods below:

const newString = str1.concat(" ").concat(str2)
// newString = "Taco Bell"

const newString = str1.concat(" ", str2)
// newString = "Taco Bell"

As you may have noticed, the concat() method takes a variable number of arguments. And each argument will be concatenated to the original string.
