4.21 TYPES OF CONTROL STATEMENTS
In JavaScript, control statements are used to control the flow of execution in a program. They allow you to make
decisions, execute code repeatedly, and handle different situations. There are three main types of control statements
in JavaScript:
Ð ÐConditional Statements: Conditional statements allow your program to make decisions based on certain conditions.
They execute specific blocks of code depending on whether a condition evaluates to true or false.
Ð ÐLooping (Iterative) Statements: Looping statements allow you to execute a block of code repeatedly until a certain
condition is met. They are useful for tasks that require repeated execution, such as iterating over arrays or executing
a block multiple times.
