tutorial 3: introduction to programming structures--functions

Notes

• tasks that are repeated are good candidtaes for being coded as a function
• tasks that are a single discreet unit are good candidates for being coded as their own function.
• parts of a function:
• name
• parameter(s)
• algorithm
• result or return value

Definitions

function

building block of code that can be called or invoked, can accept input, and implicitly or explicitly produces or returns a result.

algorithm

encoded steps of a specific task

JavaScript Syntax Example: Function

function to Celcisu(farenheit) {

var tem = (5/9) * (farenheit-32);

var report = farenheit + " degrees F is equal to " + temp + " degrees Celcius";

return report;

}
