What are some examples of using radix in JavaScript?

Can you show me some examples of using the radix parameter in JavaScript's parseInt function?

Sure! The radix parameter specifies the base of the number system. For example, parseInt('10', 2) will return 2 because '10' in binary is 2.

What about converting hexadecimal numbers?

You can use parseInt('1A', 16) to convert '1A' from hexadecimal to decimal, which will return 26.

Are there any other number systems I can use?

Yes, you can use radix values from 2 to 36. For instance, parseInt('Z', 36) will return 35.

Can you give me a complete example with error handling?

Absolutely! Here's a function that parses a number with error handling:

function safeParseInt(value, radix) {
    const parsed = parseInt(value, radix);
    if (isNaN(parsed)) {
        throw new Error('Invalid number');
    }
    return parsed;
}

This function will throw an error if the input is not a valid number.
