changing string casing javascript

 

[🤖]

In JavaScript, you can change the casing of a string using the toUpperCase() and toLowerCase() methods. Here's an example:

let myString = "Hello World!";
let upperCaseString = myString.toUpperCase(); // "HELLO WORLD!"
let lowerCaseString = myString.toLowerCase(); // "hello world!"

The toUpperCase() method will convert all characters in the string to uppercase, while the toLowerCase() method will convert all characters in the string to lowercase.

You can also change the casing of specific characters in a string using the charAt() and substring() methods, and then combining them with the toUpperCase() or toLowerCase() method. Here's an example:

let myString = "Hello World!";
let firstLetterUpperCase = myString.charAt(0).toUpperCase() + myString.substring(1); // "Hello World!"
let firstLetterLowerCase = myString.charAt(0).toLowerCase() + myString.substring(1); // "hello World!"

In this example, we're using the charAt() method to get the first character of the string, and then combining it with the rest of the string using the substring() method. We're then using the toUpperCase() and toLowerCase() methods to change the casing of the first character.
