How to use for loop in Javascript

It consists of three parts: initialization, condition, and iteration.

• Initialization: Sets the initial value of the counter variable.
• Condition: Specifies the condition that must be true for the loop to continue.
• Increment/Decrement: Updates the counter variable after each iteration.

Here is the syntax of a for loop in JavaScript:

for (initialization; condition; increment/decrement) {
  // code to execute
}

Let's break it down with an example:

for (let i = 0; i < 5; i++) {
  console.log(i);
}

In this example:

• Initialization: let i = 0 sets i to an initial value of 0.
• Condition: i < 5 ensures the loop continues as long as i is less than 5.
• Increment: i++ increases the value of i by 1 after each iteration.

The code inside the loop (in this case, console.log(i)) will execute repeatedly until the condition becomes false, printing the value of i to the console in each iteration.
