The JavaScript break statement breaks out or exits the current loop, switch statement, or a labeled block. It is a very useful statement, which helps us to exit the loop midway when a certain condition occurs. The break transfers the control to the very next statement after the loop, switch, or a labeled block.
JavaScript for loop repeats a group of statements until a specified condition evaluates to false.  The for loop allows us to specify an initialization expression, condition, and final expression as part of the loop syntax.
While & Do While statements keep executing a block of statements in a loop until a given condition evaluates to false.
The JavaScript switch statement (or switch case statement) evaluates a given expression. It then matches the result of that expression with the values in the case clause. If it finds a match, then it executes the statements associated with that matching case clause. It also executes the statements in all the case statements that follow the matching case. You can break out of a switch using the break statement or using the return statement.
JavaScript if statements run a block of code only if an evaluation of a given condition results in true. If statements can be used with else clause, If else if clause and as nested if to control the flow of the program execution.
