Format/covert JS object string to valid JSON format

Question

Given a STRING (not object) that represents JS object.

'{a: {b: 1}}' (not object but string)

Is there some simple general way to convert it to JSON {"a": {"b": 1}}? Maybe parse and covert, as JSON.parse is not applicable.

If you have no other content than this, you could take eval with parentheses around to prevent that it is interpreted as a block statement with labels.

Maybe worth a look:

When is JavaScript's eval() not evil?

var string = '{a: {b: 1}}',
    object = eval(`(${string})`);

console.log(object);

Right thanks, forgot about eval at all, anyway it is quite applicable in my case.

Try this:

var string = '{a: {b: 1}}';
eval('var obj='+string);
console.log(obj.a);
