ค่าเริ่มต้นที่ปลอดภัยของ Mojo

Mojo's default is to give you independent copies. You opt into sharing only when you truly need it. 🛡️

A safe default means the easy path is also the correct path. You avoid bugs without thinking hard about them.

Aliasing is when two names secretly share data. Value semantics blocks accidental aliasing, the root of many tricky bugs.

Because copies are independent, you can understand a function by reading just that function. Outside code cannot reach in and surprise you.

Hand a value to a function and, by default, it works on a copy. Your original is protected from quiet edits.

Code that behaves the same every time is worth more than clever sharing tricks. The safe default trades a little flexibility for trust.

Mojo is smart about copies and can optimize them away when safe. Safety here does not mean slow.

When you do want shared or mutable access, Mojo makes you ask for it explicitly. Intent is visible right in the code.

Many languages let one edit silently corrupt distant data. Mojo's value-first default removes that whole class of mistakes.

When values are independent, moving code around rarely breaks hidden links. You refactor with real confidence. ✅

Assume copies unless told otherwise. That single assumption, backed by Mojo's default, keeps reasoning simple.

Why does Mojo default to value semantics instead of sharing data between variables?

Mojo copies by default, so the easy path is the safe path. Sharing is explicit, aliasing is rare, and reasoning stays local. 🎯
