Lesson 6: Syntax

• let: Variables can be reassigned, but can’t be redeclared in the same scope.
• const: Variables must be assigned an initial value, but can’t be redeclared in the same scope, and can’t be reassigned.
• Hoisting: Before any JavaScript code is executed, all variables are hoisted, which means they're raised to the top of the function scope.
• Temporal dead zone: If a variable is declared using let or const inside a block of code, then the variable is stuck in what is known as the temporal dead zone until the variable’s declaration is processed.
• Suggested to ditch var in place of using let and const.
• Template literals: Denoted with backticks ( `` ), template literals can contain placeholders which are represented using ${expression}.
• Examples:
