In TypeScript, we can use the `toLocaleLowerCase()` method by calling it on a string variable or string literal. For example:
const myString = "HELLO WORLD";
const lowerCaseString = myString.toLocaleLowerCase();
console.log(lowerCaseString); // Output: "hello world"
In this example, we first declare a string variable `myString` with the value “HELLO WORLD”. We then call the `toLocaleLowerCase()` method on `myString` and assign the result to a new variable `lowerCaseString`. Finally, we log the value of `lowerCaseString` to the console, which outputs “hello world”.
It’s important to note that the `toLocaleLowerCase()` method is not supported in all browsers, particularly older versions of Internet Explorer. To ensure cross-browser compatibility, it’s recommended to use a polyfill or a library like `lodash` that provides a consistent implementation of the method across all browsers.
