✨ Understanding `AND (&&)` and `OR (||)` Operators in JavaScript

[Lomanu4]

Hello friends ?

In this blog, I will explain two simple and powerful tools in JavaScript: the AND (&&) and OR (||) operators. These are called logical operators and are used to check conditions.

Let’s understand them with examples that relate to real life ?‍??

? What is AND (&&)?


The && operator checks if both conditions are true

If both are true → result is true

If any one is false → result is false

? Real-Life Example:


Let’s say you want to go for a walk ?‍

You will go only if:

It is not raining

AND

You have free time ?


let isNotRaining = true;
let hasFreeTime = true;

if (isNotRaining && hasFreeTime) {
console.log("You can go for a walk! ?‍");
} else {
console.log("Stay at home! ?");
}

? If both conditions are true, the walk will happen

? If even one is false, no walk today!

? What is OR (||)?


The || operator checks if at least one condition is true

If one is true → result is true

If both are false → result is false

? Real-Life Example:


You will order food ? if:

You are hungry ?

OR

There is no food at home ?


let isHungry = false;
let noFoodAtHome = true;

if (isHungry || noFoodAtHome) {
console.log("Order food online! ?");
} else {
console.log("No need to order food. Eat at home! ?️");
}

? Only one condition needs to be true to order food

? Easy to Remember


&& → Both conditions must be true AND

|| → Only one condition needs to be true OR

? Quick Real Example


let hasLaptop = true;
let hasInternet = false;

// Check if you can work from home
if (hasLaptop && hasInternet) {
console.log("You can work from home ??");
} else {
console.log("You can't work from home ?");
}

// Check if you can still do something useful
if (hasLaptop || hasInternet) {
console.log("You can still be productive! ?");
}
Summary Table

Operator	Result is true if...
AND	Both conditions are true
OR	At least one condition is true or

I hope this blog helps you understand AND and OR operators in a fun and easy way! ?

These are very helpful when writing conditions in JavaScript.

Thanks for reading! ??
