A quirk with JavaScript closures

Read Original

This article discusses a common JavaScript pitfall where creating closures inside a loop results in all functions referencing the same variable, causing them to output the loop's final value. It explains the issue and provides solutions using Immediately Invoked Function Expressions (IIFEs) to capture the value or using the Underscore.js library for cleaner iteration.
