Weak Typing
In plain terms
Permissive typing that implicitly converts between types.
Going deeper
Weakly typed languages auto-coerce types in operations, which is convenient but can produce surprising results. It trades safety for flexibility.
Under the hood
Implicit coercion (e.g., '5' + 3) causes subtle bugs; the line between weak and dynamic typing is often blurred.
Examples
JavaScript's '==' coercion, '1' + 1 = '11', PHP loose comparisons.
Think of it like...
Like a lenient clerk who guesses what you meant and quietly swaps items, sometimes wrongly.
