JavaScript: Concatenate two strings except their first character

JavaScript Basic: Exercise-61 with Solution

Write a JavaScript program to concatenate two strings except for their first character.

This JavaScript program concatenates two input strings by omitting their first character from each string before concatenation. The length of both input strings should be at least 2.

Visual Presentation:

JavaScript:  Concatenate two strings except their first character

Sample Solution:

JavaScript Code:

// Define a function named concatenate with parameters str1 and str2
function concatenate(str1, str2) {
    // Modify str1 to exclude the first character
    str1 = str1.substring(1, str1.length);
    // Modify str2 to exclude the first character
    str2 = str2.substring(1, str2.length);
    // Return the concatenation of modified str1 and str2
    return str1 + str2;
}

 
// Call the function with sample arguments and log the results to the console
console.log(concatenate("PHP", "JS"));
console.log(concatenate("A", "B"));
console.log(concatenate("AA", "BB"));

Output:

HPS

AB

ES6 Version:

// Define a function named concatenate with parameters str1 and str2
const concatenate = (str1, str2) => {
    // Use substring to get substrings excluding the first characters
    str1 = str1.substring(1);
    str2 = str2.substring(1);
    // Concatenate the modified substrings
    return str1 + str2;
};

// Call the function with sample arguments and log the results to the console
console.log(concatenate("PHP", "JS"));
console.log(concatenate("A", "B"));
console.log(concatenate("AA", "BB"));
