Hello 

This is the day 9 of #30 days of javascrip coding, at this day I studied the Type Coercion and number and  i learned that
1-  type Coercion  is the process of converting data from one type to another while the code runs logically
2- If there is a situation in which I want to combine the variable A with the variable B Here the programming language will treat the variable a as a string and the + as a concatenate sign So the result will be in the form of a String
3- In JavaScript, all numbers are treated with double precision
4-It makes the numbers clearer and easier to understand through underscore sign
5-This is an example of the number million, which means 1 with 6 zeros next to it. The function of Sugar Syntactic is to clarify and facilitate the reading of this number. When the number is written in this way, it is read very easily and is recognized as a million.
6- Also, if you wrote the number million using floating or decimal numbers and wrote In the end, a mark and  zero will also result in a million, because the last zero will have no value
  
That's all I learned today

      Hello  This is the day 22  of #30 days of javascrip coding, at this day  I studied  Loop – While Lesson   i learned that 1-  The While Loop is similar to the For Loop in general loop performance, but the Syntax is slightly different in its shape, but the result from both is the same. 2- In the loop while, at the beginning the variable defines in the stage called initialization 3-  The while next to it is the condition, which as long as it is True , the loop remains running 4-  After that, printing is done, and then the increment process is completed, which is called Final Expression. Without its presence, the loop will remain running forever because it is responsible for increasing the value of the index until it reaches a stage where the condition is False and its fulfillment stops. 5- It is possible, if i would like, to break it as soon as the loop reaches a number.

        Hello  This is the day 26  of #30 days of javascrip coding, at this day  I studied  Function Rest Parameters Lesson   i learned that 1-  Suppose that I have an unknown number of Arguments, and every time I add an Argument, I am forced to add a new Parameter, and thus I start entering the Parameter into the calculation process. 2- This may apply, for example, if someone enters a site and wants to post his Skills, the Skill may be one, 10, or an unknown number. 3- Here comes the role of the Rest Parameters. In short, writing it consists of 3 points, then the name of the Parameter, and its purpose is to create an infinite number of Params. 4- I will also notice something that the Parameters Rest is an Array, so I can deal with it and with any Argument that forms a Value for this Para. It is an element of the Array, meaning I can use the Length and use all the properties of the Array. T hat's what I learned today  and this is the codes i have typed

        Hello  This is the day 25  of #30 days of javascrip coding, at this day  I studied  Function Default Parameters Lesson   i learned that 1-  The Default Value, if there is no value for the Parameter, it  will be Undefined 2- If you do not write a value for the age parameter, the result will be Undefined by default 3- However, if the user actually did not enter the Age, it would not make sense for it to be Undefined, and it would be better if an alternative message was printed in its place. This can be done in 3 ways, including the ES6 method. 4- The first way is to make a condition if the default age value is Undefined. This definitely indicates that the user neglected to enter the age value, because Undefined does not appear unless the user neglected to write the age. 5- Here, if the value of age becomes Undefined, meaning the user left it empty, print the place of the variable age. This is an alternative word called Unknown, so I stored it as a variable in the age so that it i
