Fundamental Question about Prompts

Morning groovers.

I am learning JavaScript from a very fundamental level up - quick question

When using a prompt and I enter for example the number 8 - will JavaScript always interpret that as in integer - unless I convert it to a string.


1 Answer


No. JavaScript will interpret 8 as a string unless you cast it to a number. The prompt method will return a

  • string value if you type something and click OK
  • null if you click cancel
  • an empty string if you click ok but did not type into the input
