I have this string

\'john smith~123 Street~Apt 4~New York~NY~12345\'

Using JavaScript, what is the fastest way to parse this into

You'll want to look into JavaScript's substr or split, as this is not really a task suited for jQuery.

well, easiest way would be something like:
```
var address = theEncodedString.split(/~/)
var name = address[0], street = address[1]
```

Zach had this one right.. using his method you could also make a seemingly "multi-dimensional" array.. I created a quick example at JSFiddle http://jsfiddle.net/LcnvJ/2/

// array[0][0] will produce brian
// array[0][1] will produce james

// array[1][0] will produce kevin
// array[1][1] will produce haley

var array = [];
    array[0] = "brian,james,doug".split(",");
    array[1] = "kevin,haley,steph".split(",");

Even though this is not the simplest way, you could do this:

var addressString = "~john smith~123 Street~Apt 4~New York~NY~12345~",
    keys = "name address1 address2 city state zipcode".split(" "),
    address = {};

// clean up the string with the first replace
// "abuse" the second replace to map the keys to the matches
addressString.replace(/^~|~$/g).replace(/[^~]+/g, function(match){
    address[ keys.unshift() ] = match;
});

// address will contain the mapped result
address = {
    address1: "123 Street"
    address2: "Apt 4"
    city: "New York"
    name: "john smith"
    state: "NY"
    zipcode: "12345"
}

Update for ES2015, using destructuring

const [address1, address2, city, name, state, zipcode] = addressString.match(/[^~]+/g);

// The variables defined above now contain the appropriate information:

console.log(address1, address2, city, name, state, zipcode);
// -> john smith 123 Street Apt 4 New York NY 12345

This isn't as good as the destructuring answer, but seeing as this question was asked 12 years ago, I decided to give it an answer that also would have worked 12 years ago.

function Record(s) {
    var keys = ["name", "address", "address2", "city", "state", "zip"], values = s.split("~"), i
    for (i = 0; i<keys.length; i++) {
        this[keys[i]] = values[i]
    }
}

var record = new Record('john smith~123 Street~Apt 4~New York~NY~12345')

record.name // contains john smith
record.address // contains 123 Street
record.address2 // contains Apt 4
record.city // contains New York
record.state // contains NY
record.zip // contains zip
