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:

JavaScript: Find the types of a specified angle.

Sample Solution:

HTML Code:

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

How to insert an item into an array at a specific index (JavaScript)?

What you want is the splice function on the native array object.

arr.splice(index, 0, item); will insert item into arr at the specified index (deleting 0 items first, that is, it's just an insert). In this example we will create an array and add an element to it into index 2:

var arr = []; arr[0] = "Jani"; arr[1] = "Hege"; arr[2] = "Stale"; arr[3] = "Kai Jim"; arr[4] = "Borge"; console.log(arr.join()); arr.splice(2, 0, "Lene"); console.log(arr.join());
