parseInt("0x10")//16 

The `parseInt()` function in JavaScript is used to parse a string and convert it into an integer. When you provide a string as an argument to `parseInt()`, it tries to interpret that string as an integer and extract the numeric value from it.

In your example, you're trying to parse the string `"0x10"`. Let's break down what happens:

1. `"0x10"` is a string that starts with `"0x"`. In JavaScript, when a string starts with `"0x"`, it is treated as a hexadecimal (base-16) number.

2. The `"0x"` prefix indicates that the number is in hexadecimal format. In this format, `0x10` represents the number 16 in base-10 (decimal) notation.

3. When you pass `"0x10"` to `parseInt()`, it recognizes the `"0x"` prefix as indicating a hexadecimal number and proceeds to convert it to decimal.

4. The result of `parseInt("0x10")` is `16`, which is the decimal equivalent of the hexadecimal number `"0x10"`.

So, `parseInt("0x10")` returns `16` because it interprets the input as a hexadecimal number and converts it to its decimal equivalent.
