What does "weakly typed" mean in programming?
weakly typed is one of the most common terms in software development. This guide explains what it means, how it is used in practice, and why it matters, with real examples from the developer world.
Definition
A language is weakly typed (or loosely typed) when it performs implicit type coercions, silently converting between incompatible types. This can lead to surprising results. JavaScript is the classic example: adding a number to a string produces a string rather than an error.
Example
"JavaScript is weakly typed, so `1 + '2'` gives `'12'` instead of an error — a common source of subtle bugs."
