how to convert string array of objects to array of objects

I have an array that I want to convert but I have no idea how to do it

how can i convert this array

const a = ['{/run:true}', '{/sleep:false}'];

in this array

const b = [{'/run':true}, {'/sleep':false}];
Solution

  • Using map and a regular expression:

    const a = ['{/run:true}', '{/sleep:false}'];
const b = a.map(s => {
  const [_,k,v] = s.match(/\{(.+):(.+)}/);
  return {[k]: JSON.parse(v)};
});
console.log(b);

    Or other way is to run a sting replacement and JSON.parse

    const a = ['{/run:true}', '{/sleep:false}'];
const b = JSON.parse("[" + a.toString().replace(/\{([^:]+)/g, '{"$1"') + "]");
console.log(b);
