JavaScript: Find the types of a specified angle

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.

JavaScript: Tips of the Day

Checks if a string is an anagram of another string (case-insensitive, ignores spaces, punctuation and special characters)

Example:

const isAnagram = (str1, str2) => {
  const normalize = str =>
    str
      .toLowerCase()
      .replace(/[^a-z0-9]/gi, '')
      .split('')
      .sort()
      .join('');
  return normalize(str1) === normalize(str2);
};
console.log(isAnagram('iceman', 'cinema')); // true

Output:

true
