What is conditional logic in JavaScript?

Conditional logic in JavaScript allows you to execute different code based on certain conditions using statements like if, else, and switch.

Can you give me an example of using an if statement?

Sure! Here's a simple example:

let age = 18;
if (age >= 18) {
    console.log('You are an adult.');
} else {
    console.log('You are a minor.');
}

What about switch statements?

A switch statement is useful for executing different code based on the value of a variable. Here's an example:

let fruit = 'apple';
switch (fruit) {
    case 'banana':
        console.log('Banana is yellow.');
        break;
    case 'apple':
        console.log('Apple is red or green.');
        break;
    default:
        console.log('Unknown fruit.');
}

How do I handle multiple conditions?

You can use logical operators like && (AND) and || (OR) to combine conditions. For example:

let score = 85;
if (score >= 90) {
    console.log('Grade: A');
} else if (score >= 80 && score < 90) {
    console.log('Grade: B');
} else {
    console.log('Grade: C or lower');
}
