+## Arrow Blocks
+
+To enhance conciseness, Hi adopts the \`=>\` ("fat arrow") from JavaScript for single-expression blocks. This provides a shorthand for a block that immediately returns the value of its expression, perfect for callbacks and functional patterns.
+
+It's a direct replacement for \`(params) { ^ expression }\`.
+
+\`\`\`javascript
+// Standard block
+add: (a, b) { ^ a + b }
+
+// Equivalent Arrow Block
+add: (a, b) => a + b
+
+// Useful for functional helpers
+numbers: [1, 2, 3]
+doubled: numbers.map((n) => n * 2)
+_(doubled) // [2, 4, 6]
