Welcome back, Explorer! Today's adventure dives into JavaScript, exploring function invocation, calling independent functions within a function, and working with default argument values.
A function invocation refers to calling or triggering a function. Invoking independent functions within another combines their outputs. If no specific value is passed, default argument values are used. Are you ready to decode these concepts? Let's get started!
Remember, a function acts only when we invoke or call it. Consider the function sayHello, invoked by sayHello(). Here's an illustration:
Function invocation in JavaScript is akin to using a recipe — you 'invoke' the recipe to make the cookies!
Very often, we need to combine the outputs of different functions. That's when invoking independent functions within another becomes handy.
Imagine you have two distinct functions, sayHello and sayGoodbye. Now, crafting a greet function to invoke sayHello and sayGoodbye would look like this:
