Function Declarations vs Expressions

Closures allow functions to access variables from an outer function scope even after the outer function has returned
Every function in JavaScript creates a closure
Closures consume memory because they prevent variables from being garbage collected
Closures only work with function expressions, not function declarations
The false statement is that closures only work with function expressions, not function declarations. In fact, closures work with all functions in JavaScript, regardless of whether they are created using function declarations, function expressions, or arrow functions. A closure is formed whenever a function accesses variables from its outer lexical environment. This capability is a fundamental part of how JavaScript functions work, not limited to a specific syntax for creating functions. Both function declarations (`function name() {}`) and function expressions (`const name = function() {}`) can create closures if they reference variables from their outer scopes. The ability to form closures is related to the lexical scoping mechanism in JavaScript, not to the specific syntax used to define the function. This is why closures are such a powerful and ubiquitous pattern in JavaScript programming.
