Why if the numeric value in the array contains more than 2 points, then the interpreter considers it a string?

Question

JavaScript

Please explain this behavior, and how can I convert these strings to a numeric value.
The fact is that I need to iterate over the array and if there is a text value there, delete it, leaving only numbers

Answer 1

strings with more than one dot can only be converted to a number with data loss. ParseInt, parseFloat, look for the function that suits you
