Object Properties Sparsing

Description

Object Properties Sparsing transforms object literal's declarations into member expressions.

Code Annotation Example

// @jscrambler enable objectPropertiesSparsing

Example

Consider the following example:

var a = {
  b: 1,
  c: {
    d: 2
  }
};

Object Properties Sparsing will break down the object's properties and create the following expressions:

var e = {};
e.b = 1;
e.c = {};
e.c.d = 2;
var a = e;

Consider combining this transformation with obfuscation transformations to harden the resulting code, making it more resilient to automated de-obfuscator tools and troublesome to understand by a human. You may find useful to combine this transformation with Dot to Bracket Notation and string transformations to strengthen the result.
