Convert double Quotes array "[]" to Pure Array object Node JS, BodyParser

Question

so here is the problem : I am passing a list/array of objects from front end to my node js back end.

This is how it looks on the front end : [{"sample1": "this", "apple2" : eat},{"sample2": "thisIs2", "apple3" : eatFruits}]

but when it is passed to the backend , its converted to String,something like this:
"[{"sample1": "this", "apple2" : eat},{"sample2": "thisIs2", "apple3" : eatFruits}]"

So when I run a for loop in my node js, the length is calculated as each characters. what do i do to get the pure array and the contents in the array. Thanks

@ask4you Anytime I use that, it throws this error .. SyntaxError: Unexpected token t in JSON at position 2 — that_flutter_guy

@lusc It didn't help. I tried already, I used JSON.parse, it throws this error ... SyntaxError: Unexpected token t in JSON at position 2 — that_flutter_guy

Sounds like you're incorrectly stringifying it then. You'll need to debug how it's being sent. The string you've posted is indeed invalid due to missing quotes around the object values eat and eatFruits, but that could easily be a typo on your part — pilchard

"[{"sample1": "this", "apple2" : eat},{"sample2": "thisIs2", "apple3" : eatFruits}]"
Your object is the "stringified" JSON. Means whole JSON object represented as string

e.g.

const jsonObj = [{"id": 1, "name": "John"}, {"id": 2, name: "Jane"}];
const strigified = JSON.stringify(jsonObj);
console.log(strigified);

output

'[{"id":1,"name":"John"},{"id":2,"name":"Jane"}]'

This can be reversed by parsing this string as JSON

const original = JSON.parse(strigified);
console.log(original);

output

[{"id": 1, "name": "John"}, {"id": 2, name: "Jane"}]

JSON.strigify() & JSON.parse() are exactly reciprocal methods...
