Decision Making in TypeScript

Decision making is a crucial part of software development, and TypeScript provides many options for making decisions in your code. From simple if-else statements to complex Switch statements, there are lots of ways to create the logic you need in your code. Plus, using TypeScript can help you write better code and reduce errors. In this article, we’ll explore decision making in TypeScript and look at some examples of how to use it in your code.

The If Statement

The simplest form of decision making in TypeScript is the if statement. It enables you to check a condition and then execute code based on the result. Here’s an example:

if (myNumber > 10) {
    console.log('My number is greater than 10.');
}

In this example, if the value of myNumber is greater than 10, the console will print “My number is greater than 10.” Otherwise, nothing happens. You can also add an else statement to execute alternate code if the condition is not met:

if (myNumber > 10) {
    console.log('My number is greater than 10.');
} else {
    console.log('My number is not greater than 10.');
}

The Switch Statement

The switch statement is a more complex form of decision making in TypeScript. It is useful when you want to compare a single value against multiple cases. Here’s an example:

switch (myNumber) {
    case 1:
        console.log('My number is one.');
        break;
    case 2:
        console.log('My number is two.');
        break;
    default:
        console.log('My number is something else.');
}

In this example, the switch statement checks the value of myNumber, and depending on what it finds, it will execute different code. If the value is 1, the console will print “My number is one.” If it’s 2, it will print “My number is two.” If none of the cases match, the default block will be executed, printing “My number is something else.”

Conclusion

Decision making is an important part of writing software, and TypeScript provides many ways to implement it. From simple if-else statements to complex switch statements, there is a lot of flexibility in how you can make decisions in your code. With TypeScript’s help, you can write better code and reduce errors.
