APPSYNC_JS support for parseInt, parseFloat and Number()

[WolfWalter]

I tried to convert my object keys from string to numbers, but got "The code contains one or more errors. " as a response when I tried to use parseInt, parseFloat or Number().

myReturnObject = {}
stringFromPreviousResult = "52.525243"
myReturnObject.property = Number(stringFromPreviousResult)

What is the proper way to convert a string to a number with APPSYNC_JS runtime?

As a workaround I used the unary operator: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Unary_plus

const test = '123';
const testNumber = +test;

Number.isNaN(Number("asdf"))

Appears to work as well. Any reason we couldnt add this to util? as a safeParser or something? I know this is the community so I think I'm just screaming into the void here 🙃

Edit - this does NOT work as expected when deployed. Amazing.

Note the above does not work, amazing.

const value = +someString doesnt allow for whitespace, so maybe +someString.trim() is a good idea.
