Hey im trying to convert a string that holds numbers but the string has commas in it and I'm trying to remove those commas as well.
let why = "42,343,324"
console.log(typeof why) // string
let noCommas = parseFloat(why.replace(/,/g, ''));
console.log(noCommas) // 42343324but when I replace why value with a prop value, it gives me an error saying Cannot read property 'replace' of null
let why = visitsPerPerson
console.log(typeof why)
let noCommas = parseFloat(why.replace(/,/g, ''));
console.log(noCommas)
Output: Cannot read property 'replace' of null
The prop is a string value that holds numbers returned from an API
the prop itself doesn't return null but returns a string with numbers in it and can verify when I console log:
console.log(visitsPerPerson)
I re-produced the second code snippet and got expected output:
NaN (Not a Number), which is correct and the expected result for "visitsPerPerson".
Did I understand something wrong?
let why = "visitsPerPerson";
console.log(typeof why); // string
let noCommas = parseFloat(why.replace(/,/g, ''));
console.log(noCommas); // NaN (Not a Number, which is correct)
