Function Hoisting vs Let Const Hoisting

Developers should learn function hoisting to write predictable JavaScript code and debug issues related to scope and execution order meets developers should learn this concept when working with modern javascript (es6+) to prevent bugs related to variable access before declaration, especially in block-scoped contexts like loops or conditionals. Here's our take.

Function Hoisting

Nice Pick

Developers should learn function hoisting to write predictable JavaScript code and debug issues related to scope and execution order

Pros

• It's essential when working with legacy codebases or when mixing function declarations and expressions, as it affects how functions are accessible in different parts of the code
• Related to: javascript, scope

Cons

• Specific tradeoffs depend on your use case

Let Const Hoisting

Developers should learn this concept when working with modern JavaScript (ES6+) to prevent bugs related to variable access before declaration, especially in block-scoped contexts like loops or conditionals

Pros

• It's essential for writing robust code in frameworks like React, Vue, or Node
• Related to: javascript, ecmascript-6

Cons

• Specific tradeoffs depend on your use case

The Verdict

Use Function Hoisting if: You want it's essential when working with legacy codebases or when mixing function declarations and expressions, as it affects how functions are accessible in different parts of the code and can live with specific tradeoffs depend on your use case.

Use Let Const Hoisting if: You prioritize it's essential for writing robust code in frameworks like react, vue, or node over what Function Hoisting offers.

The Bottom Line

Function Hoisting wins

Developers should learn function hoisting to write predictable JavaScript code and debug issues related to scope and execution order
