Node.js Controls - Loops

In Node.js, control loops are used to repeatedly execute a block of code until a certain condition is met. Control loops are essential for creating dynamic and responsive applications that can react to changing data or user input.

Types of control loops that you can use in Node.js

For Loops
- for (initialization; condition; increment/decrement)
- for (let key in object)
- for (const value of object)
- foreach
While Loops
Do-While Loops

For Loops

for (initialization; condition; increment/decrement)

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

for (let i = 1; i <= 5; i++) {
    console.log(i);
}

Nested For Loops

for (let i = 1; i <= 10; i++) {
    for (let j = 1; j <= 10; j++) {
        console.log(i + " * " + j + " = " + i * j);
    }
}

While Loops

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

let i = 1;

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

Do-While Loops

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

let i = 1;

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