How to convert String to Uppercase in TypeScript ?

To convert a string to uppercase in TypeScript, you can use the toUpperCase() method of the String class.

In this example,

We declare a variable named str1 with a string value of "Hello World".
We then use the toUpperCase() method of the string object str1 to convert it to uppercase and store the result in the variable upperCaseStr1.
The toUpperCase() method returns a new string with all characters converted to uppercase.
Finally, we log the value in upperCaseStr1 to the console.

let str1: string = "Hello World";
let upperCaseStr1: string = str1.toUpperCase();
console.log("Uppercase of given string is: " + upperCaseStr1);

Uppercase of given string is: HELLO WORLD

In this example,

We declare a variable named str2 with a string value of "apple".
We then use the toUpperCase() method of the string object str2 to convert it to uppercase and store the result in the variable upperCaseStr2.
The toUpperCase() method returns a new string with all characters converted to uppercase.
Finally, we log the value in upperCaseStr2 to the console.

let str2: string = "apple";
let upperCaseStr2: string = str2.toUpperCase();
console.log("Uppercase of given string is: " + upperCaseStr2);

Uppercase of given string is: APPLE
