## JavaScript Basic: Exercise-86 with Solution

Write a JavaScript program to find the types of a given angle.

Types of angles:
• Acute angle: An angle between 0 and 90 degrees.
• Right angle: An 90 degree angle.
• Obtuse angle: An angle between 90 and 180 degrees.
• Straight angle: A 180 degree angle.

Pictorial Presentation: Sample Solution:

HTML Code:

``````<!DOCTYPE html>
<html>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width">
<title>Find the types of a specified array</title>
<body>

</body>
</html>
```
```

JavaScript Code:

``````function angle_Type(angle) {
if(angle < 90) {
return "Acute angle.";
}
if(angle === 90) {
return "Right angle.";
}
if(angle < 180) {
return "Obtuse angle.";
}
return "Straight angle.";
}

console.log(angle_Type(47))
console.log(angle_Type(90))
console.log(angle_Type(145))
console.log(angle_Type(180))
```
```

Sample Output:

```Acute angle.
Right angle.
Obtuse angle.
Straight angle.
```

Flowchart: ES6 Version:

``````function angle_Type(angle) {
if(angle < 90) {
return "Acute angle.";
}
if(angle === 90) {
return "Right angle.";
}
if(angle < 180) {
return "Obtuse angle.";
}
return "Straight angle.";
}

console.log(angle_Type(47))
console.log(angle_Type(90))
console.log(angle_Type(145))
console.log(angle_Type(180))
``````

## JavaScript: Tips of the Day

Classes/function constructors

```class Person {
constructor() {
this.name = 'Owen';
}
}

Person = class AnotherPerson {
constructor() {
this.name = 'Eddie';
}
};

const member = new Person();
console.log(member.name);
```

We can set classes equal to other classes/function constructors. In this case, we set Person equal to AnotherPerson. The name on this constructor is Eddie, so the name property on the new Person instance member is "Eddie".
