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