How to read signatures

How it works

The m.parseQueryString method creates an object from a querystring. It is useful for handling data from URL

var data = m.parseQueryString("a=hello&b=world")

// data is {a: "hello", b: "world"}

Boolean type casting

This method attempts to cast boolean values if possible. This helps prevents bugs related to loose truthiness and unintended type casts.

var data = m.parseQueryString("a=true&b=false")

// data is {a: true, b: false}

Leading question mark tolerance

For convenience, the m.parseQueryString method ignores a leading question mark, if present:

var data = m.parseQueryString("?a=hello&b=world")

// data is {a: "hello", b: "world"}

Deep data structures

Querystrings that contain bracket notation are correctly parsed into deep data structures


// data is {a: ["hello", "world"]}
