while loop

The while loop loops through a block of code as long as a specified condition is true.

Syntax

while(condition) {
    // your code
}

example

let i = 0;
while(i < 10) {
    console.log('the value of i = ',i);
    i++;
}

output

The value of i = 0
The value of i = 1
The value of i = 2
The value of i = 3
The value of i = 4
The value of i = 5
The value of i = 6
The value of i = 7
The value of i = 8
The value of i = 9

At i = 10 condition becomes false and while loop terminates.
