easy-json-parse

Are you still worried about the long code with try {} catch {}? like this:

const jsonString = 'easy';
let json;
 
try {
  json = JSON.parse(jsonString);
} catch (e) {
  json = {};
}
 
console.log(json.xxx);

or

const jsonString = null;
let json;
 
try {
  json = JSON.parse(jsonString) || {};
} catch (e) {
  json = {};
}
 
console.log(json.xxx);
