Julia 跨平台移动应用框架
基本CSS3文件、JS库和各个平台的运行库构成。不像PhoneGap，Julia不仅仅包含调用本机代码的接口层，它还包含Model-View-Controller（MVC）支持，Delegation支持，OAuth支持，异步数据库存取接口，HTML选择符（类jQuery调用接口），HTML模版（允许嵌入JS代码）等应用开发必备的API接口。
Julia 0.5.2 和 0.6.0-rc1 发布了，本次更新包括了很多新的语言特性。
部分新的语言特性如下：
New type system capabilities (#8974, #18457)
Type parameter constraints can refer to previous parameters, e.g. type Foo{R<:Real, A<:AbstractArray{R}}. Can also be used in method definitions.
New syntax Array{T} where T<:Integer, indicating a union of types over all specified values of T (represented by a UnionAll type). This provides behavior similar to parametric methods or typealias, but can be used anywhere a type is accepted. This syntax can also be used in method definitions, e.g. function inv(M::Matrix{T}) where T<:AbstractFloat. Anonymous functions can have type parameters via the syntax ((x::Array{T}) where T<:Real) -> 2x.
Implicit type parameters, e.g. Vector{<:Real} is equivalent to Vector{T} where T<:Real, and similarly for Vector{>:Int} (#20414).
Much more accurate subtype and type intersection algorithms. Method sorting and identification of equivalent and ambiguous methods are improved as a result.
