Hello 
This is the fourth day of #30 days of javascrip coding, at this day i learned that
1- I used console.log(type of " ") function To identify the type of data that was printed 
2- I learned that there are many types of data We will learn about it in the following lines
3- The first type of data called string and It must be written in  double quotes mark 
4- The second type of data called number and It should not be written in double quotes mark So as not to be treated like string
5-The third type of data called object in a form of array                       6- The fourth type of data called object a nd his type is object object  and his type is object                                                                               7- There are other types of data such as boolean value an undefined and null                                                                                                   This is the codes that i used

  Hello  This is the day 13  of #30 days of javascrip coding, at this day  I studied  Comparison Operators  and   i learned that 1- In this lesson, i learned about comparison signs or operators, which have a very important role in the world of conditioning and decision-making. 2- The equal sign (=) is used to assign a specific value to a specific variable 3-  The purpose of the (==) is to compare values to each other, even if their types are different 4-  The (=!) means not Equal and the result appears as true or false 5-  The (===) means a complete match, and the Identical here you are comparing the value and also the data type. and the result appears as true or false 6-  In the case of Identical not or the ( ==! ) The question is whether this value and its type match this value and its type or not  and the result appears as true or false 7-there are another  Comparison Operators such as the  greater than s...

      Hello  This is the day 11  of #30 days of javascrip coding, at this day  I studied the  Math Object  and   i learned that 1-  Just as we talked previously about the Function Number and the properties within it that can be used to deal with numbers, today we will talk about the Object Math, which contains properties or tools that can be used to implement various tasks. 2-The first of these features or tools is round() function, which is mainly intended to round decimal numbers to the nearest whole number based on the number after the sign. 3- There are two other types of tools: the ceil and the floor, and here there is a fundamental difference between them 4- The ceil is an indication of the ceiling, that is, rounding to the largest value, regardless of the number after the decimal point 5- The floor is a reference to the floor, meaning rounding to the smallest value, regardless of the number after the ...
