array of object string convert to array of object only javascript

Question

I have a string that contains an array of object '[{letter: a, number: 1}, {letter: b, number: 2}]' I'm trying to make it literally a array of object using JSON.parse() but I'm getting an error saying

`SyntaxError: Unexpected token l in JSON at position 2`

My code

let a = '[{letter: \'a\', number: 1}, {letter: \'b\', number: 2}]'

let b = JSON.parse(a)

console.log(b)

I can't even use a.split(',') because I have a , inside the object

my expected output was

[{letter: 'a', number: 1}, {letter: 'b', number: 2}]

how can I fix it?

In JSON keys must be strings, so you have to reformat your JSON string like this:

[{"letter": "a", "number": 1}, {"letter": "b", number: 2}]
