I asked a question about currying and closures were mentioned. What is a closure? How does it relate to currying?
When you create the closure, i is a reference to the variable defined in the outside scope, not a copy of it as it was when you created the closure. It will be evaluated at the time of execution. Most of the other answers provide ways to work around by creating another variable that won't change the value for you.
How to ensure closures created in a loop capture the value of the loop ...
A closure is a pairing of: A function and A reference to that function's outer scope (lexical environment) A lexical environment is part of every execution context (stack frame) and is a map between identifiers (i.e. local variable names) and values. Every function in JavaScript maintains a reference to its outer lexical environment. This reference is used to configure the execution context ...
And here comes the closure part: The closure of a lambda expression is this particular set of symbols defined in the outer context (environment) that give values to the free symbols in this expression, making them non-free anymore.
A closure can actually be any function within another function, and its key characteristic is that it has access to the scope of the parent function including it's variables and methods.
2 A closure is an implementation technique for representing procedures/functions with local state. One way to implement closures is described in SICP. I will present the gist of it, anyway. All expressions, including functions are evaluated in an environement, An environment is a sequence of frames. A frame maps variable names to values.
A closure allows you to bind variables into a function without passing them as parameters. Decorators which accept parameters are a common use for closures. Closures are a common implementation mechanism for that sort of "function factory". I frequently choose to use closures in the Strategy Pattern when the strategy is modified by data at run ...
A closure is just one function that has access to a bunch of state, but a class has many methods which share access to the same state. Many languages (e.g. Java, Python, etc.) have local classes, which can capture variables from surrounding scope just like a closure; so they are strictly more general than closures.
A closure carries parts of a local state into a function of some sort, think of it as passing by reference. A callback is meant to notify you about certain change and it redirects program flow. The closure could modify local state but you would never get processor time to handle that, like you would with a callback.
A closure is a function value created from a possibly nested function declaration or function expression (i.e. lambda expression) whose body contains may one or more references to variables declared in an outer scope.

The Strait of Hormuz disruption is affecting more than oil and gas, with impacts across key commodities. Here are nine materials most exposed.
But the impacts of climate change vary greatly between countries and population groups. This climate crisis is a deeply unfair one, with the poor being disproportionately affected. The countries with the fewest resources are likely to bear the greatest burden in terms of loss of life and relative effect on investment and the economy.
