How does JavaScript's parseInt function work?
An example of an AI chatbot conversation about JavaScript's parseInt function.
Can you explain how the parseInt function works in JavaScript?
Sure! The parseInt function in JavaScript converts a string into an integer. It takes two arguments: the string to be converted and the radix (base) for the numeral system.
What happens if the string can't be converted?
If the string can't be converted to an integer, parseInt will return NaN (Not-a-Number). For example, parseInt('abc') will return NaN.
Can you give me an example of using parseInt with a radix?
Of course! If you use parseInt('10', 2), it will interpret '10' as a binary number and return 2.
Is there a way to handle NaN values when using parseInt?
Yes! You can check if the result is NaN using the isNaN function. For example, if you do let result = parseInt('abc'); isNaN(result) will return true.
