In the world of programming, control flow is a fundamental concept that allows us to dictate the behavior of our code based on certain conditions. One of the most common and essential control flow structures in JavaScript is the If…Else statement. This powerful tool enables developers to make decisions and execute different blocks of code depending on whether a particular condition is true or false.
At its core, the If…Else statement is incredibly simple, yet its applications are vast and varied.
