What are common errors when using parseInt in JavaScript?
An example of an AI chatbot conversation about common errors with parseInt in JavaScript.
What are common errors when using parseInt in JavaScript?
Some common errors include not specifying the radix, using non-numeric strings, and expecting parseInt to handle decimals.
Can you explain why not specifying the radix is a problem?
Not specifying the radix can lead to unexpected results, as parseInt may interpret the string in base 8 or 10 depending on its format.
What happens if I pass a decimal number to parseInt?
parseInt will truncate the decimal part and return only the integer portion. For example, parseInt('3.14') returns 3.
Are there better alternatives to parseInt?
Yes, you can use Number() or parseFloat() for more predictable behavior with numbers, especially with decimals.
