I attempted to use regex to try and replace multiple zeros occurring at the start of a number with a single zero and multiple decimal elements with a single decimal element
Please help me see where i am going wrong
Here is a link to my code:
Hello there,
I am just wondering why you have seperate regexes to match the same thing:
/(^0)\1{2,}/
/^0+/
And
/(\.)\1{2,}/
/\.+/
I would change the regex you have in the match methods to be the same as those in the replace. I do not see why you would match one thing, and replace another.
Before i was trying to replace the unneeded characters with an empty string. Hence the regexes being different 
This makes more sense now
Though it’s throwing an error
calc.input.match is not a function
I figured the String.prototype.match function would work since my input is in string format
Edit:
I changed calc.input.replace(/0)\1{2,}/, 0) to calc.input.replace(/0)\1{2,}/, "0")
Still getting the error
Why do you assume it is always a string? You begin by setting its initial state to a number. So, if it changes to anything but if (calc.input === 0) {, and it is not a string, the error will come up.
I’m using the evaluate function from the mathjs library. The function takes in a string as a parameter. That’s why i assume it is always a string.
I’ve reset the initial state to a string and the condition for my first if statement to a string as well. Thank you for your input so far
Ah, this would again cause problems because my click event
Edit:
changing the initial state and condition to string means i also have to change the value being passed when the click event is executed. Thank you for this. I will try that and see what happens
