A function is a block of code. It performs a specific task.

Stop repeating your code. Put it in a function. Call it when you need it.

Learn these two terms:

• Parameters: Variables you write when you create a function.
• Arguments: Real values you pass when you call a function.

Example: Parameters: rice, masala, chicken. Arguments: Basmati Rice, Spicy Masala, Chicken.

Use return to send a value back from a function.

JavaScript uses hoisting. It moves declarations to the top before the code runs.

• Function declarations move fully. You call them before they appear in the code.
• Var declarations move but stay undefined.
• Let and const do not work this way.
