Difference Between JavaScript's "let" and "const" Keywords

When it comes to JavaScript, the 'let' and 'const' keywords are used for variable declaration, but they have some key differences:

• 'let' keyword: Allows the variable to be reassigned or updated within its scope.
• 'const' keyword: Declares a read-only reference to a value, meaning the variable cannot be reassigned or updated.

It is important to choose between 'let' and 'const' based on whether you need a variable to be mutable or immutable in your web development project.
