The JavaScript String charCodeAt() function returns the Unicode value of the character at the specified index in a string. The index is zero-based, meaning the first character in the string has an index of 0, the second character has an index of 1, and so on. The returned value is an integer between 0 and 65535, representing the Unicode value of the character. If the specified index is out of range, the function returns NaN (Not a Number). This function is useful for working with strings that contain non-ASCII characters, such as accented letters or characters from non-Latin scripts.

Javascript String charCodeAt in Kotlin With Example Code
JavaScript’s `charCodeAt()` method is used to return the Unicode value of the character at a specified index in a string. In Kotlin, we can achieve the same functionality using the `code` property of a `Char` object.
To get the Unicode value of a character at a specific index in a string, we can use the following code:
val str = "Hello, World!"
val index = 1
val unicode = str[index].code
println("The Unicode value of the character at index $index is $unicode")
In this example, we first define a string `str` and an index `index` to specify which character we want to get the Unicode value of. We then use the `code` property of the character at the specified index to get its Unicode value and store it in the `unicode` variable. Finally, we print out the Unicode value using string interpolation.
It’s important to note that the `code` property returns the Unicode value of a single character, not the entire string. If you want to get the Unicode values of all the characters in a string, you can use a loop to iterate over each character and get its Unicode value using the `code` property.
Overall, using the `code` property of a `Char` object in Kotlin is a simple and effective way to achieve the same functionality as JavaScript’s `charCodeAt()` method.
Equivalent of Javascript String charCodeAt in Kotlin
In conclusion, the Kotlin programming language provides a powerful and efficient way to work with strings. The charCodeAt() function in Kotlin is the equivalent of the JavaScript function of the same name. It allows developers to retrieve the Unicode value of a character at a specific index in a string. This function is useful for a variety of applications, including text processing, data analysis, and encryption. With Kotlin’s robust string handling capabilities, developers can create high-quality applications that are both reliable and efficient. Whether you are a seasoned developer or just starting out, Kotlin’s string functions are a valuable tool to have in your programming arsenal.
