JavaScript Objects Pass By Reference, Codecademy, Passing Variables Assigned to Objects as Arguments

In this JavaScript tutorial we look at, JavaScript Objects Pass By Reference, Codecademy, Passing Variables Assigned to Objects as Arguments. We learn that when we pass variables that are assigned to objects into functions as arguments, these are objects passed by reference. When we have functions that change object properties, this will actually mutate our object permanently, even when our object is assigned a const variable. When we try and use a function to reassign objects passed in, this will not reassign our object properties. This is because when we pass object variables into our function arguments, our parameter name becomes a reference to our object's memory location, but not of our object variable. Understanding pass-by reference in JavaScript is essential when trying to master JavaScript. Learning how objects behave under the hood will help you best with debugging your code. Make sure to practice JavaScript Object Pass By Reference and understand JavaScript Object pass by reference before continuing on. Learning what pass by reference is referring to is a key fundamental in learning programming, and mastering it will help you better comprehend javascript and programming! Thanks for watching JavaScript Objects Pass By Reference, Codecademy, Passing Variables Assigned to Objects as Arguments.
