JavaScript Program to print multiplication table of a number

In this article, we are given a number n as input, we need to print its table.

Examples:

Input :  5
Output : 5 * 1 = 5
         5 * 2 = 10
         5 * 3 = 15
         5 * 4 = 20
         5 * 5 = 25
         5 * 6 = 30
         5 * 7 = 35
         5 * 8 = 40
         5 * 9 = 45
         5 * 10 = 50

Input :  8
Output : 8 * 1 = 8
         8 * 2 = 16
         8 * 3 = 24
         8 * 4 = 32
         8 * 5 = 40
         8 * 6 = 48
         8 * 7 = 56
         8 * 8 = 64
         8 * 9 = 72
         8 * 10 = 80
         8 * 11 = 88
         8 * 12 = 96

These are the following methods to print table:

Method 1: Using Javascript Loops

In this approach we are using for loop for printing the table of the given integer. We will create a for loop and we start the iteration form 1 till 10. and print the fomat of the table.

Example: This example shows the implementation of the above-explained approach.

Javascript

// Javascript program to print
// table of a number

let n = 5;
for (let i = 1; i <= 10; ++i)
    console.log(n + " * " + i +
        " = " + n * i);

Output

5 * 1 = 5
5 * 2 = 10
5 * 3 = 15
5 * 4 = 20
5 * 5 = 25
5 * 6 = 30
5 * 7 = 35
5 * 8 = 40
5 * 9 = 45
5 * 10 = 50

Method 2: Using Recursion in Javascript

In this approach, we are using recursion to print the table. we will take the integer and the iteration value as a parameter in the recursive function. and we will print the table until it reaches to the basecase.

Example 1: This example shows the implementation of the above-explained approach.

Javascript

function print_table(n, i = 1) {
    if (i == 11) // Base case
        return;
    console.log(n + " * " + i + " = " + n * i);
    i++;  // Increment i
    print_table(n, i);
}

// Driver Code
let n = 5;
print_table(n);

Output

5 * 1 = 5
5 * 2 = 10
5 * 3 = 15
5 * 4 = 20
5 * 5 = 25
5 * 6 = 30
5 * 7 = 35
5 * 8 = 40
5 * 9 = 45
5 * 10 = 50

Example 2: This example show the multiplication table of 8.

Javascript

let n = 8;

// Change here to
// change result.
let range = 12;
for (let i = 1; i <= range; ++i)
    console.log(n + " * " + i +
        " = " + n * i);

Output

8 * 1 = 8
8 * 2 = 16
8 * 3 = 24
8 * 4 = 32
8 * 5 = 40
8 * 6 = 48
8 * 7 = 56
8 * 8 = 64
8 * 9 = 72
8 * 10 = 80
8 * 11 = 88
8 * 12 = 96
