- We define a string object
strObjusing theStringconstructor with the value'Hello'. - We use the
toString()method to get the string representation of the object. - The result is stored in the variable
str. - We log
strto the console using theconsole.log()method.

const strObj = new String('Hello');
const str = strObj.toString();
console.log(str);Output

For example,
- We define a string variable
strwith the value'Hello World'. - We use the
toString()method to get the string representation, although it will remain unchanged. - The result is stored in the variable
result. - We log
resultto the console using theconsole.log()method.
JavaScript Program
const str = 'Hello World';
const result = str.toString();
console.log(result);Output
Hello World

strwith the value'Hello\nWorld'which contains a newline character. - We use the
