# V8 Engine

### **Interpreters:**

     Reads the js code line by line and converts to binary code and provides the result.

    **Cons:**  Execution time for repeated code will be longer.

### Compilers:

    Reads the entire code in the js file and converts to another language and provides the result.

   **Pros:**  Less execution time is taken for the repeated code execution.
