Summary
Scope: var is function-scoped, let is block-scoped.
Hoisting: var is hoisted and initialized with undefined, let is hoisted but not initialized.
Re-declaration: var allows re-declaration, let does not.


Using let is generally preferred over var due to its block-scoping behavior and the reduced risk of bugs related to re-declaration and hoisting issues.
