    DIFFERENT BLOCKS OF BLOCKS EDITOR

                      Built-in blocks are always available and provide basic tools for logic, text, variables
                      and more in the Blocks Editor.

                      1.  Control Blocks: These blocks manage the flow of the program using conditions,

                          loops and event triggers. They help you decide what happens and when. Example:

                              if         Tests a given condition. If the condition is true, it runs the specified
                           then
                                         blocks; if not, it skips them.
                              if
                           then          Tests a given condition. If it is true, the blocks in the then part run;

                           else          if it is false, the blocks in the else part run.

                      2.  Logic Blocks: These blocks allow you to make decisions using true/false values. You

                          can compare values and use logical operations like AND, OR and NOT. Example:

                                     Represents  the  constant  value true.  It is  used  to  set  the  Boolean
                         true
                                     properties of components or assign a condition value to a variable.

                                     Represents  the  constant  value  false. It  is  used  to  set  the  Boolean
                         false
                                     properties of components or assign a variable to represent a condition.

                      3.   Math Blocks: These blocks perform basic and advanced mathematical calculations.

                          You can add, subtract, multiply, divide and more. Example:

                                          This block lets you display numbers in decimal form and can also
                         decimal   0
                                          show them in other formats, such as binary or hexadecimal.

                                          This block compares two values to check if one is greater than,
                              =
                                          less than or equal to the other.

                      4.   Text Blocks: These blocks are used to work with words and characters. You can

                          join, split, change and compare text. Example:

                                         This string can contain any characters (letters, numbers or other
                                         special characters). On App Inventor it will be considered a Text object.

                               join      Appends all of the inputs to make a single string. If there are no
                                         inputs, it returns an empty string.
