Answer 1

You could split and iterate the array.

const
    string = 'Option 1|false|Option 2|false|Option 3|false|Option 4|true',
    result = [];

for (let i = 0, a = string.split('|'); i < a.length; i += 2) {
    const
        option = a[i],
        value = JSON.parse(a[i + 1]);
    result.push({ option, value });
}

console.log(result);

Answer 2

You can use .match() on the string with a regular expression to get an array of the form:

[["Option 1", "false"], ...]

And then map each key-value into an object like so:

const str = "Option 1|false|Option 2|false|Option 3|false|Option 4|true";
const res = str.match(/[^\|]+\|[^\|]+/g).map(
  s => (([option, value]) => ({option, value: value==="true"}))(s.split('|'))
);

console.log(res);

Answer 3

const options = 'Option 1|false|Option 2|false|Option 3|false|Option 4|true';

const parseOptions = options => options.split('|').reduce((results, item, index) => {
  if (index % 2 === 0) {
    results.push({ option: item });
  } else {
    results[results.length - 1].value = item === 'true';
  }
  return results;
}, []);

console.log(parseOptions(options));

Answer 4

str='Option 1|false|Option 2|false|Option 3|false|Option 4|true';
str=str.split('|');
result=[];
for(var i=0;i<str.length;i += 2){
result.push({"option":str[i],"value":str[i+1]=="true"?true:false})
}
console.log(result)
