Lines 943 to 957 in bf1c66b

    
           if e != nil { 
        
           	return offset, e 
        
           } 
        
           if o == 0 { 
        
           	break 
        
           } 
        
           if t != NotExist { 
        
           	cb(v, t, offset+o-len(v), e) 
        
           } 
        
           if e != nil { 
        
           	break 
        
           }

how to indicate that cb return an error for ArrayEach, like ObjectEach do.

           // Step 3: find the associated value, then invoke the callback 
        
           if value, valueType, off, err := Get(data[offset:]); err != nil { 
        
           	return err

           }

I had the same issue, willing to fail fast on some JSON parsing, I've put together a PR #214 feel free to comment and review

v1.4.0: ArrayEachErr, Escape/SetString, wildcards, JSONPath, GetArray…

Implemented in v1.4.0 — ArrayEachErr(data, func(value []byte, vt ValueType, offset int, err error) error { return myErr }, keys...). See: https://github.com/buger/jsonparser/releases/tag/v1.4.0
