  - equals
```
public boolean equals(java.lang.Object other)
```
    Overrides:
    
    equals in class java.lang.Object
  - isEqual
```
public boolean isEqual(java.lang.Object other)
```
    JavaScript definition of equality (==). JSValue.equals() and JSValue.isEqual() represent the Java and JavaScript definitions, respectively. Normally they will return the same value, however some classes may override and offer different results. Example, in JavaScript, new Float32Array([1,2,3]) == new Float32Array([1,2,3]) will be false (as the equality is only true if they are the same physical object), but from a Java util.java.List perspective, these two are equal.
    
    Parameters:
    
    other - the value to compare for equality
    
    Returns:
    
    true if == from JavaScript perspective, false otherwise

    Parameters:
    
    other - The value to test against
    
    Returns:
    
    true if values are strict equal, false otherwise
