The JavaScript String concat() function is used to concatenate two or more strings and return a new string. It takes one or more string arguments and joins them together in the order they are provided. The original strings are not modified, and the resulting concatenated string is returned. The concat() function can be called on any string object or can be used as a standalone function. It is a useful tool for combining strings in JavaScript programming. Keep reading below to learn how to Javascript String concat in Kotlin.

Javascript String concat in Kotlin With Example Code
String concatenation is a common operation in programming. In Kotlin, you can concatenate strings using the + operator or the plus() function. However, if you are coming from a JavaScript background, you might be used to using the concat() method to concatenate strings. In this blog post, we will show you how to use the concat() method in Kotlin.
The concat() method is not available in Kotlin’s standard library, but you can easily add it as an extension function to the String class. Here’s an example:
fun String.concat(other: String): String {
return this + other
}
This function takes another string as a parameter and returns a new string that is the concatenation of the two strings. You can call this function on any string object:
val str1 = "Hello"
val str2 = "world"
val result = str1.concat(str2)
println(result) // Output: HelloWorld
Alternatively, you can define the concat() function as an infix function, which allows you to use it with the infix notation:
infix fun String.concat(other: String): String {
return this + other
}
val str1 = "Hello"
val str2 = "world"
val result = str1 concat str2
println(result) // Output: HelloWorld
Using the concat() method can make your code more readable and easier to understand, especially if you are used to using it in JavaScript. However, keep in mind that the + operator and the plus() function are still the preferred ways to concatenate strings in Kotlin.
Equivalent of Javascript String concat in Kotlin
In conclusion, Kotlin provides a powerful and efficient way to concatenate strings using the `plus()` operator. This operator allows you to easily combine multiple strings into a single string without the need for any additional functions or methods. Additionally, Kotlin also provides the `StringBuilder` class which can be used for more complex string manipulations. By using these features, Kotlin developers can easily create and manipulate strings in their applications with ease and efficiency. Overall, Kotlin’s string concatenation capabilities make it a great choice for developers looking to build robust and scalable applications.
