JavaScript: Create a new string without the first and last character of a given string

JavaScript Basic: Exercise-60 with Solution

Write a JavaScript program to create a new string without the first and last characters of a given string.

This JavaScript program takes an input string and returns a new string with the first and last characters removed. The length of the input string should be at least 2.

Visual Presentation:

Sample Solution:

JavaScript Code:

// Define a function named without_first_end with parameter str
function without_first_end(str) {
  // Use substring to get a portion of the string excluding the first and last characters
  return str.substring(1, str.length - 1);
}

// Call the function with sample arguments and log the results to the console
console.log(without_first_end('JavaScript'));
console.log(without_first_end('JS'));
console.log(without_first_end('PHP')); 

Output:
