Example 1: Multiplication Table Up to 10

// program to generate a multiplication table

// take input from the user
let number = parseInt(prompt('Enter an integer: '));

//creating a multiplication table
for(let i = 1; i <= 10; i++) {

    // multiply i with number
    result = i * number;

    // display the result
    console.log(`${number} * ${i} = ${result}`);
}

Output

Enter an integer: 3
3 * 1 = 3
3 * 2 = 6
3 * 3 = 9
3 * 4 = 12
3 * 5 = 15
3 * 6 = 18
3 * 7 = 21
3 * 8 = 24
3 * 9 = 27
3 * 10 = 30

In the above program, the user is prompted to enter an integer value. Then, the for loop is used to iterate through 1 to 10 to create a multiplication table.

Example 2: Multiplication Table Up to a Range

/* program to generate a multiplication table
upto a range */

// take number input from the user
let number = parseInt(prompt('Enter an integer: '));

// take range input from the user
let range = parseInt(prompt('Enter a range: '));

//creating a multiplication table
for(let i = 1; i <= range; i++) {
    result = i * number;
    console.log(`${number} * ${i} = ${result}`);
}

Output

Enter an integer: 7
Enter a range: 5
7 * 1 = 7
7 * 2 = 14
7 * 3 = 21
7 * 4 = 28
7 * 5 = 35

In this above example, the user is prompted to enter an integer and also a range to which they want to create a multiplication table.

The user enters an integer(here 7) and a range(here 5). Then a multiplication table is created using a for loop to that range.
