It was renamed JavaScript on December 4, 1995. It was first released under the name of LiveScript as part of Netscape Navigator 2.0 in September 1995. JavaScript was created by Netscape programmer Brendan Eich. Collaborate with others and create powerful visuals today.JavaScript is a cross-platform, object-oriented scripting language developed by Netscape.

The second feature is Definiteness. If there is no ending, the algorithm is not complete. First is Finiteness, which means the algorithm should have an ending. The algorithm has five features. The algorithm is a set of step-by-step clear instructions to solve a problem. Before dive deeper into the expressions of algorithm, I will briefly talk about algorithm.

To access the hierarchy chart maker, simply click on the data tab located on the left-hand panel of the editor and choose the flowchart tool. Last is the Effectiveness, the algorithm should not be very complex, the less step it use, the better it is.Click on the Create button on this page or open any project on the Visme dashboard. The third and the fourth features are the Input and Output, which is the data you have and the result you can get. Like the instruction вЂњadd waterвЂќ is not a good order, because I can either add 100 ml water, or 1000 ml water.

Bu using this algorithm, we need maximum 6 times to find the right answer.Here is another important concept from this activityвЂ”array. The algorithm of this game is guess the 13th or the 14th letter in the first round, and exclude half of the letters, then guess the letter in the middle of the second range, and exclude half of the letters in the second range, so on and so forth. Students will guess the letter of the other studentвЂ™s ship in turn, and the other student will tell the number of the ship the student guess and if it is larger or smaller than the number of the correct ship.

In the game, students try to guess the right value by narrow down the range and search different addresses. The computer can check the value in the array by access a certain address. In the Battleship game, the address is the number, and the value is the letter of that ship.

During the process, if any step goes wrong, we need to go back to the last step and revise it.Now we can talk about pseudocode. Implementation means to execute the selected solution. Selection means to select the best alternative. Development means to explore variousalternatives. Identification means to identify, understand and formulate the problem.

The third convention is that when you use notations like вЂњifвЂќ and вЂњloopвЂќ, you need to write the condition (if there is one) after the notation, and write the instructions that will be executed if the condition is achieved in the line below the notation. The second convention is that all the pseudocode keywords are in lower case, for example if, loop and so on. The first convention is that all the variables are in the upper case, for example NUM can represent a number that the user inputed. We use text to represent logical relationships, and here are some notations and conventions in creating the pseudocode.First I will talk about some of the conventions.

By following this logic, we can find the largest and smallest number. All the things I just talk about may be a little bit abstract, but you can see in the examples below.We wrote some pseudocode in class, and I will show the most interesting one as a demonstration of the former content.In this example, I used the array I talked before to store the five user inputs, and the basic logic of finding the largest and smallest number is: first define the larger number between the first two numbers as X and define the smaller number as I, then compare these two numbers with the three remaining numbers one by one, and if the number is larger than X, then set X as that number if the number is smaller than I, then set I as that number. There is also else if, which actually add a вЂњifвЂќ if the first condition is not fulfilled. Last, if-then-else has a more complex logic, which means if the condition after вЂњifвЂќ is fulfilled, then a set of instruction under that line of instruction will be executed if the condition after вЂњifвЂќ is not fulfilled, the instruction under вЂњelseвЂќ will be executed. Loop means it will repeat a set of instructions again and again until the condition after вЂњwhileвЂќ is not fulfilled.

The most valuable thing I learnt this week is the tase table which gives me a well organized way to test algorithm, which, I believe, will be very important in the later study. I learnt some new ways of logical thinking, and created some more advanced programs. You can see the result from the table, and this pseudocode actually works.In the last class, we reviewed the flowchart, which is much more basic, you can see the concept from the blog post in Grade 10, and here is a example of using flowchart to represent an algorithm, and the algorithm it represent is still example 6.In this week, we gained more detailed information about the Pseudocode, Trace Table, and Flowchart. Then we can start the tracing process and fill the outcome of each step into the table. Then we fill the initial values in the second row, this time we assign some random values to the 5 addresses.
