Answer 1

var i = "[{a:1,b:2}]",
    j = i.replace(/([a-zA-Z0-9]+?):/g, '"$1":').replace(/'/g,'"'),
    k = JSON.parse(j);

console.log(k)

// => declaring regular expression

[a-zA-Z0-9] => match all a-z, A-Z, 0-9

(): => group all matched elements

$1 => replacement string refers to the first match group in the regex.

g => global flag
