'let' and 'const' are JavaScript keywords that were introduced in ES6 that allow you to declare variables that are limited to the scope of a block statement. The 'var' keyword, on the other hand, declares a variable globally or locally to an entire function. let and const are similar when it comes to scoping rules, but variables declared with const are read-only. const variables cannot be re-assigned after initially being declared.
