Javascript String toLowerCase in Kotlin With Example Code

JavaScript’s `toLowerCase()` method is a useful tool for converting strings to lowercase. In Kotlin, we can achieve the same functionality using the `toLowerCase()` extension function.

To use this function, we simply call it on a string variable or string literal. For example:

val myString = "HELLO WORLD" val lowerCaseString = myString.toLowerCase()

In this example, `lowerCaseString` will now contain the value “hello world”.

It’s important to note that the `toLowerCase()` function creates a new string with all characters converted to lowercase. The original string remains unchanged.

If you need to perform case-insensitive comparisons or searches, using `toLowerCase()` can be a helpful step in ensuring consistent results.

Overall, the `toLowerCase()` function is a simple yet powerful tool for working with strings in Kotlin.
