# JavaScript basics if...else statement

I sometimes forget that I write about content in a medium to advanced kind of matter.

In these JavaScript basics series, I'll be looking at some more fundamental topics of JavaScript, so you get a good idea of how to use these methods.

In this article, we'll be looking at using if...else statements in JavaScript.

## A JavaScript if statement

An if statement can be used to execute code only when a specific condition is met.

Let's say we have a variable and want to evaluate whether it's true or false.

```js
let our_var = true;
if(our_var === true) {
	// Execute this code if true
	console.log('Value is true);
}
```

In this case when we are checking boolean values, we don't need to specify the specific value so we can do this:

```js
if(our_var) {
	// Execute this code if true
	console.log('Value is true);
}
```

You can also check if the value is false, like this:

```js
if(!our_var) {
	// Execute this code if false
	console.log('Value is false);
}
```

We can even write this as a one-liner, but most linters will want to see the brackets for neatness.

```js
if (our_var) console.log('Value is true');
```

## JavaScript if...else statement

Often you also want to execute some code if the first condition is not met.
We can achieve this by using the else statement as well.

```js
if (our_var) {
  console.log('Condition is met');
} else {
  console.log('Condition is not met, fallback?');
}
```

And you can even bind another if statement to this else, making it super powerful.

Let's say you want to check multiple conditions after each other.

```js
if (our_var) {
  console.log('first condition met');
} else if (our_second_var) {
  console.log('Second condition was met!');
} else {
  console.log('No condition was met');
}
```

You can make these as big as you want, but often you might want to consider using other solutions for bigger statements.

## JavaScript Ternary Operator

The JavaScript ternary operator is a quick way to express conditions and is often used for shorthand if...else.

The Syntax looks like this:

```js
condition ? truthy : falsy;
```

If we take our example, we could write code like this:

```js
our_var ? console.log('Condition is met') : console.log('Condition not met');
```
