1. In javascript by default variables are global even though if they are defined inside function
2. You can make a variable only specific to function by adding 'var' ahead of variable
3. var can be used if we want to change variable
For Example: var message = "hi"
var message = "hello"
This wont return any error
4. let can be used only once for a variable
For Example: let message = "hi"
let message = "hello"
This will return an error saying "Duplicate Declaration"
But however you can change value of message.
For Example: let message = "hi"
message = "hello"
This wont return any error and message value will be changed to "hello"
5. const can be used only once for a variable and unlike let we cant change value of variable
For Example: let message = "hi"
message = "hello"
This will return an error saying "Assignment to constant variable: message "
But if we declare cont array then we can add values to the array however we can t change entirely
For Example: let message = ["hi"]
message.push("hello")
So now value for message would be ["hi", 'hello"]
6. We can add strings but we cannot remove [-] from string
