# Interpreter ¶

Go back

Literally a way to write a simple parser.

• ➡️ : String.valueof(...) in java
• ✅ : good if simple language
• 🚫 : hell if language is complex

## Another point of view ¶

The main idea is that each element of the syntax is a class or a value, but an expression will most likely be evaluated as

(evaluate left) operator (evaluate right)


for a binary operator, and you should keep that in mind while coding. For instance

• $1 + 2 + 3$
• is the same as
• $(1+2) + (3)$
• we are evaluating $1+2 = 3$
• we are evaluating $3 = 3$
• then we are evaluating $3+3=6$
