Scope and usage of let , var & const keywords

for changing of values of var

var name =" jai";
var name = "ram" ;
console.log(name)

This console prints the value of ram , var overrides the value of name. This causes problem while debugging the code and increases the ambiguity of code .

For changing values of let

let  name =" jai";
let name = "ram" ;
console.log(name)

We can see error that identifier name has been already taken , so let keyword not allowing reinitialization of identifier name , we need to use different names for the let keywords.

For changing values of const


 const name ="jai";
  const name =" ram";
console.log(name)

This console shows error that name has already assigned .

**So its better to use const for variables

let for if there is any changing of values

var is least prioritized **

For usage of var in scope

var  fun ;
for (var  i = 0; i < 3; i++) {
  if(i ==2){ fun =() =>{
    return i; }
  }

}
console.log(fun());

when var is declared it is considered as global variable . The above console returns the value of 3 , because as the for loop iteration changes the i value by increment , so var i takes i value and returns as 3 .

For usage of let in scope

let  fun ;
for (let  i = 0; i < 3; i++) {
  if(i ==2){ fun =() =>{
    return i; }
  }

}

console.log(fun());

Let is considered as block variable (within in the scope )
From the above code it returns the value of i as 2 ;
logically this result was correct .

From above Global scope of two keywords we see they were returning variables with different outputs

let keyword update was came in ES6 , we need to use let instead of var because of let keyword scope , updating values ,

So Finally

     ## const >>> let >>> var

Benefits of having routines

Benefits of “Clarity Routines”
What you can expect from following the routines:
• Increased productivity
• Increased well being
• Being more present
• Improved creativity
• Waking up excited
• Peace of mind
• More energy
• Feeling light
• Less worries
• Better sleep
• Calmness
Who does not want that?
let's get to the routines

                     Daily Morning

1. Drink water
Yes it’s the most basic thing but it still is vital. When you wake
up your body is dehydrated and thus does not function
optimally. It is no surprise you will feel tired if your body is not
properly hydrated. So your first action in the morning should be
to drink a big glass of water. I like to squeeze half a lemon into
my water. It gives me valuable vitamin C and makes me feel
extra recharged.

2. Gratitude
Remember that your mind is a blank state in the morning?

So, instead of grabbing your phone and drowning your mind
with cheap dopamine hits and messages you need to answer
we are going to fill it with gratitude. Every morning write down
three different things you are grateful for (use a pen and a
notebook for this). We have so many blessings in this life that
we too often forget. Making time in the morning to remind
yourself of all the blessings you got is a great way to start the
day with a positive attitude and a feeling of abundance.

3. Move your body
To really get you started for the day you need to get your blood
flowing. You do this by moving your body. Because a healthy
body is a body that moves. I personally go for a walk in the
morning to move and get some fresh air. Another option is to
do Yoga. It does not only provide increased blood flow but the
stretching also makes you more flexible. The health benefits of
Yoga and walking are too many to be listed right here so just
do it and you feel it for yourself! You can do any other
movement of your choice but do 10 minutes of movement
every morning MINIMUM!

4. Meditate
When our mind is empty in the morning it is a great time to
meditate and to connect to our awareness to let it shine
through the rest of the day. Every morning sit down for at least
10 minutes and meditate. You can pay attention to your breath
or just observe your thoughts, any meditation is fine.

I personally start by observing my breath for a few minutes and
then I visualize my ideal life in concrete detail. After I have done
that I set a clear intention for the day in my mind and the
thoughts and actions I want to be aware of during the day. This
allows me to go through the day with a clear purpose and a
clear mind.

5. Journal
There is so much in your head. Put it on paper. Clear your
mind. Journaling is a great way to organize your thoughts and
keep track of how your life is going. Life happens fast and if we
do not pay attention it goes by without us even noticing it. By
journaling we can keep track and put a stop to the altering of
memories. Looking back at journal entries will give you the
opportunity to re-evaluate what worked and what didn’t. Live
consciously, write your ideas and experiences down!
