What is the syntax of if-else in JavaScript?

Can you explain the syntax of if-else statements in JavaScript?

Sure! The basic syntax of an if-else statement in JavaScript is:

if (condition) {
    // code to be executed if condition is true
} else {
    // code to be executed if condition is false
}

What if I want to add more conditions?

You can use else if to add more conditions. Here's an example:

if (condition1) {
    // code for condition1
} else if (condition2) {
    // code for condition2
} else {
    // code if none of the conditions are true
}

Can you give me a practical example?

Of course! Here's a simple example:

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