Convert JS object to JSON string

Question

If I defined an object in JS with:

var j={\"name\":\"binchen\"};

How can I convert the object to JSON? The output string should be:

Answer 1

convert str => obj

const onePlusStr = '[{"brand":"oneplus"},{"model":"7T"}]';

const onePLusObj = JSON.parse(onePlusStr);

convert obj => str

const onePLusObjToStr = JSON.stringify(onePlusStr);
