Display All Prime Numbers between 1 and 100 in JavaScript

In this example we display all the prime numbers between 1 and 100.

A prime number is a positive integer that is only divisible by 1 and itself

Example

// program to print prime numbers between 1 and 100
console.log(`The prime numbers are:`);

// looping from 1 to 100
for (let i = 1; i <= 100; i++) 
{
    let flag = 0;

    // looping through 2 to number
    for (let j = 2; j < i; j++) 
	{
        if (i % j == 0) 
		{
            flag = 1;
            break;
        }
    }

    // if number greater than 1 and not divisible by other numbers
    if (i > 1 && flag == 0) 
	{
        console.log(i);
    }
}

This will display the following
