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
The prime numbers are: 2 3 5 7 11 13 17 19 23 29 31 37 41 43 47 53 59 61 67 71 73 79 83 89 97
