Put the learning moves in the order that makes the concept easiest to apply.

Statement identifiers are reserved words (cannot be used as variable names or any other things).

JavaScript statements start with a statement identifier to identify the action to be performed.

Statement	Description
{ }	Creates an block of statements
async function	Creates an AsyncFunction object
async function*	Creates an AsyncGeneratorFunction object
await using	Declares local variables that are asynchronously disposed
break	Exits a switch or a loop
class	Declares a class
const	Declares a variable with a constant value
continue	Breaks one iteration (in the loop) if a specified condition occurs, and continues with the next iteration in the loop
debugger	Stops the execution of JavaScript, and calls (if available) the debugging function
do...while	Executes a block of statements and repeats the block while a condition is true
for	Loops through a block of code a number of times
for...in	Loops through the properties of an object
for...of	Loops through the values of an iterable object
for await...of	Loops over async iterable objects
function	Declares a function
function*	Creates a GeneratorFunction object
if...else...else if	Marks a block of statements to be executed depending on a condition
import	Defines a read-only import of a module
import attributes	Defines how a module should be loaded
let	Declares a variable
return	Stops the execution of a function (and returns a value)
switch	Marks a block of statements to be executed depending on different cases
throw	Throws (generates) an error
try...catch...finally	Marks the block of statements to be executed when an error occurs in a try block, and implements error handling
using	Declares local variables that are synchronously disposed
var	Declares a variable
while	Marks a block of statements to be executed while a condition is true
