The key to mastering any programming language is knowing how to work with data — understanding, transforming, and manipulating all types of data structures and types (Primitive, Non-primitive and User-defined/abstract Datatypes)
Knowing the concept is more important than knowing the Syntax
| Feature | Interpreter | Compiler |
|---|---|---|
| 🔄 Execution | Executes code line-by-line | Translates entire code at once into machine code |
| 🕒 Speed (Run time) | Slower (interprets every time) | Faster (compiled once, runs many times) |
| Stops at the first error | Shows all errors after compilation | |
| 🧪 Use Case | Scripting, dynamic coding (e.g., Python) | Performance-critical software (e.g., games, system apps) |
| 🔤 Output | No separate file — runs directly | Produces an executable file (e.g., .exe) |
| 🧰 Examples | Python, JavaScript, PHP, Ruby, Node.js | C, C++, Rust, Go, Java* |
