Type: `boolean` Default: `false`
##### :warning: This option greatly affects the performance up to 2x slower runtime speed. Use [`controlFlowFlatteningThreshold`](#controlflowflatteningthreshold) to set percentage of nodes that will affected by control flow flattening.

Unicode escape sequence increases code size greatly. It is recommended to disable this option when using [`stringArrayEncoding`](#stringarrayencoding) (especially with `rc4` encoding).
## Option Presets
### High obfuscation, low performance
Performance will 50-100% slower then without obfuscation
```javascript
{
compact: true,
controlFlowFlattening: true,
controlFlowFlatteningThreshold: 1,
debugProtection: true,
debugProtectionInterval: true,
disableConsoleOutput: true,
rotateStringArray: true,
selfDefending: true,
stringArray: true,
stringArrayEncoding: 'rc4',
stringArrayThreshold: 1,
unicodeEscapeSequence: false
}
```
### Medium obfuscation, optimal performance
Performance will 30-35% slower then without obfuscation
```javascript
{
compact: true,
controlFlowFlattening: true,
controlFlowFlatteningThreshold: 0.75,
debugProtection: false,
debugProtectionInterval: false,
disableConsoleOutput: true,
rotateStringArray: true,
selfDefending: true,
stringArray: true,
stringArrayEncoding: 'base64',
stringArrayThreshold: 0.75,
unicodeEscapeSequence: false
}
```
### Low obfuscation, High performance
Performance will slightly slower then without obfuscation
```javascript
{
compact: true,
controlFlowFlattening: false,
debugProtection: false,
debugProtectionInterval: false,
disableConsoleOutput: true,
rotateStringArray: true,
selfDefending: true,
stringArray: true,
stringArrayEncoding: false,
stringArrayThreshold: 0.75,
unicodeEscapeSequence: true
}
