Extend Predicates

Description

A predicate is an expression that evaluates to either true or false. This transformation extends the predicates in your code with opaque predicates making them harder to understand.

Code Annotation Example

// @jscrambler enable extendPredicates

Examples

The following example is a while statement with a simple predicate:

var i = 0;
while (i < 10) {
  i++;
}

After extending the predicate i < 10 the resulting predicate becomes harder to understand. The following example is a possible output:

var i = 0;
while (i < 10 && 5II.m()[8][1] == h5II.X()[7][2]) {
  i++;
}
