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, as it allows you to access the Unicode values of those characters.

Javascript String charCodeAt in TypeScript With Example Code
JavaScript is a popular programming language used for web development. One of the most commonly used data types in JavaScript is the string. In TypeScript, which is a superset of JavaScript, strings are also a fundamental data type.
One useful method that can be used with strings in JavaScript and TypeScript is the `charCodeAt()` method. This method returns the Unicode value of the character at a specified index in a string. The Unicode value is a unique number assigned to each character in the Unicode standard.
To use the `charCodeAt()` method in TypeScript, you can simply call it on a string variable and pass in the index of the character you want to get the Unicode value for. For example:
let myString = "Hello World";
let unicodeValue = myString.charCodeAt(1);
In this example, the `charCodeAt()` method is called on the `myString` variable with an index of 1. This will return the Unicode value of the second character in the string, which is the letter “e”. The Unicode value of “e” is 101.
It’s important to note that the `charCodeAt()` method returns NaN (Not a Number) if the specified index is out of range or if the string is empty. Therefore, it’s a good practice to check the return value of this method before using it in your code.
In conclusion, the `charCodeAt()` method is a useful tool for working with strings in JavaScript and TypeScript. It allows you to get the Unicode value of a specific character in a string, which can be helpful in a variety of scenarios.
Equivalent of Javascript String charCodeAt in TypeScript
In conclusion, the charCodeAt function in TypeScript is an equivalent of the same function in JavaScript. It is a useful tool for developers who want to access the Unicode value of a character in a string. With TypeScript, developers can take advantage of the language’s strong typing and object-oriented features to write more robust and maintainable code. By using the charCodeAt function in TypeScript, developers can ensure that their code is both efficient and accurate, making it easier to build high-quality applications. Overall, the charCodeAt function in TypeScript is a valuable addition to any developer’s toolkit, and it is worth exploring further to see how it can be used to improve your code.
