Solution
The statement that is NOT true about let and const in ES6 is: "They are hoisted to the top of the block".
In JavaScript, unlike var, let and const are not hoisted to the top of the block. Hoisting is a JavaScript mechanism where variables and function declarations are moved to the top of their containing scope before code execution. However, let and const remain uninitialised at the beginning of execution whilst still being scoped to the block. This is what's known as the Temporal Dead Zone, a period between entering scope and being declared where they can't be accessed.
