You can expect some beginner-friendly content in this course, along with some learning paths.
I strongly believe in practical application. Therefore, I will not bore you with facts, long theories, or rants about which parts of JavaScript I consider good or bad. This course is all about getting our hands dirty and understanding how JavaScript works inside out.
This highly practical course will start off from covering basic programming concepts in Javascript to introducing JavaScript with HTML and CSS.  In addition, you will also get an insight into JavaScript history and its growth in the Software World.

JavaScript in Practice: Getting Started

"JavaScript gives you full access to your data structures in memory." 
Is the above statement correct or not?

“JavaScript gives you full access to your data structures in memory.” 
Is the above statement correct or not?

Recall the reference and value types and select a type through which primitive types are passed.

Recall the reference and value types and select a type through which primitive types are passed.

```
var employee = [
    { name: 'Mark Klaus', age: 22 }
];

function increaseAge( employee ) {
    employee += 1;
}
 
console.log( 'Before:', employee[0].age );
increaseAge( employee );
console.log( 'After:', employee.length );
```
Considering the above code, select the correct output.

<pre><code>var employee = [
 { name: 'Mark Klaus', age: 22 }
];

function increaseAge( employee ) {
 employee += 1;
}
 
console.log( 'Before:', employee[0].age );
increaseAge( employee );
console.log( 'After:', employee.length );
</code></pre>
Considering the above code, select the correct output.

```
function increaseAge( employee ) {
    employee += 3;
}
 
console.log( 'Before:', employee[0].age );
increaseAge( employee );
console.log( 'After:', employee[0].age );
```

```
function increaseAge( employee ) {
    employee[0].age += 3;
}
 
console.log( 'Before:', employee[0].age );
increaseAge( employee );
console.log( 'After:', employee[0].age );
```

```
function increaseAge( employee, age ) {
    employee[0].age = age;
}
 
console.log( 'Before:', employee[0].age );
increaseAge( employee, 25 );
console.log( 'After:', employee[0].age );
```

```
var employee = [
 { name: 'Mark Klaus', age: 22 }
];

function increaseAge( employee ) {
 employee += 1;
}
 
console.log( 'Before:', employee[0].age );
increaseAge( employee );
console.log( 'After:', employee.length );
```
What changes are required if we want the age of the employee to be `25` after the function call?

You must select the most appropriate one.

<pre><code>var employee = [
 { name: 'Mark Klaus', age: 22 }
];

function increaseAge( employee ) {
 employee += 1;
}
 
console.log( 'Before:', employee[0].age );
increaseAge( employee );
console.log( 'After:', employee.length );
</code></pre>
