Week 10 and 11

Week 10

A JavaScript function is a chunk of code designed to perform a particular task, such as calculation. Every function has a name, a list of parameters to the function, enclosed in parentheses and separated by commas, and statements that define the function, inside curly brackets.

Here is a example of a simple function

console.log(‘Hello World’);

If you want to have an alert box, you can type:

alert(“Hello World”);

if you want to have the words, write:

document.write(‘Hello World”);

Week 11

Why do we use if/else statements?

It is used to perform different actions based on different conditions.

The if/else statement executes a block of code if a specified condition is true. If the condition is false, another block of code can be executed.

It works like:

if name = “Joe”;
{
alert(“hey Joe”);
}
else if (name = “Bob”);
{
alert(“Hey Bob”)
}
