The differences between toString() and String()

The main difference between .toString() and String() is how they handle null and undefined values, as well as their usage.

1. .toString():

   const myNumber = 123
   console.log(myNumber.toString())
   // Expected output: "123"
   
   const myObject = {
     name: 'John',
     age: 30,
     city: 'New York'
   }
   
   console.log(myObject.toString())
   // Expected output: [object Object]
   
   const myNull = null
   console.log(myNull.toString())
   // Expected output: Uncaught TypeError: Cannot read properties of null (reading 'toString')
   

2. String():

   const myNumber = 123
   console.log(String(123))
   // Expected output: "123"
   
   const myObject = {
     name: 'John',
     age: 30,
     city: 'New York'
   }
   
   console.log(String(myObject))
   // Expected output: [object Object]
   
   const myNull = null
   console.log(String(myNull))
   // Expected output: "null"
