JavaScript and Type Conversion

JavaScript is a dynamic-type language:

We can assign any type of value to a variable. We can also change the type of a variable at any time and any position in the code. Let’s say we have assigned a string value to a variable, and then we want to change the type of that variable to a number.


              123
            
let totalPrice = "thousand";
totalPrice = 1000;
console.log(totalPrice);

The boolean variables can only have true or false as their values.
The typeof operator allows us to see the type of value stored in a variable.
JavaScript is a dynamic-type language, so we can change the type of data in it.
