The ABC of programming
What is a Script and how do I create one?
A script is a series of instructions that a computer can follow to achieve a goal. You could compare scripts to any of the following:
1- Recipes
2- Handbooks
3- Manuals
WRITING A SCRIPT
To write a script, you need to first state your goal and then list the tasks that need to be completed in order to achieve it.
Start with the big picture of what you want to achieve, and break that down into smaller steps.
1- DEFINE THE GOAL
First, you need to define the task you want to achieve. You can think of this as a puzzle for the computer to solve.
2- DESIGN THE SCRIPT
To design a script you split the goal out into a series of tasks that are going to be involved in solving this puzzle. This can be represented using a flowchart. You can then write down individual steps that the computer needs to perform in order to complete each individual task (and any information it needs to perform the task), rather like writing a recipe that it can follow.
3- CODE EACH STEP
Each of the steps needs to be written in a programming language that the compu ter understands. In our case, this is JavaScript.
Tasks
Once you know the goal of your script, you can work out the individual tasks needed to achieve it. This high-level view of the tasks can be represnted using flowchart.
Steps
Each individual task may be broken down into a sequence of steps. When ypu are ready to code the script,these steps can then be translated into individual lines of code.
