Have you Ever Confused about Using a Different kind of loops in JavaScript
No Problem Today we clearing the confusion
Let's Print 1-100 numbers using a different Kind of loops.
First We Print 100 numbers using For Loop.
for(let i=0; i<=100;i=i+1){
console.log(i)
}
Let's talk about what is the use of above code.
for loop takes three optional expressions
1) Initialization: we are initializing our value - (let i=0);
2) Condition: On which condition iteration if the condition is true
then the loop continues otherwise loop stop running.(i<=100);
3) Final expression: How loop increments or decrements on each iteration (i=i+1)
Inside the for loop, we are logging the value on each iteration.
Without for loop, we need to write 100 numbers manually 1 by 1 using
for loop, it only takes 2 lines of code.
Lets Solve the same problem using While loop.
let n=1
while(n<=100){
console.log(n);
n=n+1;
}
while loop runs only if something is true.Otherwise it doesn't enters
inside the loop.
We first initialized a value to the variable n with 1.
while loop only takes a single expression which is a condition(n<=100).
It only runs up to n value is equal to the 100.
On line 2 we are incrementing n on each iteration.
Now let's solve the same problem using if and while loop.
let enter=true;
let n=1;
if(enter){
while(n<=100){
console.log(n);
n=n+1;
}
}
if condition also runs on the basis of the truthy values.
- In our above problem enter is true so it enters the loop.
- Inside the if condition we placed a while loop.
How if condition works in daily life. In our day to day life,
we are making decisions like if time is 9 am I need to eat breakfast.
if time is 12 am I need to eat lunch.
Have you thinking about if-else. if time is 9 am I need to eat breakfast
else I need to do some other things(brush, bathing,etc..).
Hope you guys love these
