⚡️ Understanding the 5 loops of JavaScript
🔁 Loops offer a quick & easy way to do something repeatedly.
1. JavaScript For loop
Repeats a block of code as long as a certain condition is met.
Typically, used to loop through a block of code a specific amount of times.
2. JavaScript while loop
Loops through a block of code as long as the specified condition evaluates to true. As soon as the condition fails, the loop is stopped.
3. JavaScript do…while loop
The do…while loop is a variant of the while loop, which evaluates the condition at the END of each loop iteration.
With a do…while loop the block of code is executed ONCE, and THEN the condition is evaluated.
🔁 Loops offer a quick & easy way to do something repeatedly.
The 5 loops in JavaScript essentially do the same thing: — they repeat an action a certain number of times. However, they have important differences.
Let’s dive in!
