Javascript Loops (for, while, do-while)

JavaScript loops allow you to execute a block of code multiple times. There are three types of loops in JavaScript:

for loop:

A for loop is used to execute a block of code a specific number of times.

Syntax:

for (initialization; condition; increment) {
  // code to be executed
}

The initialization statement is executed one time only before the loop starts.
The condition statement defines the condition for executing the loop.
The increment statement is executed every time after the loop has been executed.

Example:

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

Output:

A while loop is used to execute a block of code as long as the condition is true.

Syntax:

while (condition) {
  // code to be executed
}

Example:

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

Output:

A do-while loop is used to execute a block of code at least once, and then repeatedly execute the block of code as long as the condition is true.

Syntax:

do {
  // code to be executed
}
while (condition);

The condition statement defines the condition for executing the loop.

Example:

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

Output:

In all three loops, the break statement is used to exit the loop, and the continue statement is used to skip one iteration of the loop.
