how to convert string array of objects to array of objects-CodePudding

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}];

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);

Created this simple function to do exactly that

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

// desired output
const b = [{ run: true }, { sleep: false }];

const c = a.map(item => {
    const key = item.match(/\w /)[0];
    const value = item.match(/true|false/)[0];
    return { [key]: value === 'true' };
});

console.log(c);

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

const output = a.map(item => {
    const normalize = item.replaceAll("{", "").replaceAll("}", "")
    const splitedStr = normalize.split(':');
    const key = splitedStr[0];
    const value = splitedStr[1];
    return {[key]: value}
})

console.log(output)

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

const c = a.map(item => {
  return {
    ['/'   item.split(':')[1].split('{')[0]]: item.split(':')[1].split('}')[0]
  };
});

console.log(c);
