System and method for segregating data in a dynamic programming language

Systems and methods are for segregating data and code implemented in a dynamic language, where the segregated data and code operate in an environment, where the environment and the segregated data and code are controlled using a common dynamic language. The environment is implemented in the common dynamic language, the environment including a framework, the framework including a plurality of properties. A visible framework property is identified that is visible to applications. An invisible framework property is identified that is not visible to the applications. A first application is implemented in a first sandbox within the environment, wherein the first application is implemented in the common dynamic language, wherein the first application is unable to access the invisible framework property, and wherein the first application is able to access the visible framework property.
