In this lesson we take a look at, "Difference Between Arrays with let and const in JavaScript, Use let and const with Array, Codecademy". This JavaScript lesson is from the Arrays section of Codecademy and is called "Arrays with let and const". In it, we learn the difference between arrays declared using let, and arrays declared using const. We learn that arrays that are declared using let can have their values reassigned and you can even create a new array out of it. We learn that an array that is declared a const, can only be reassigned an element within the array but we are not able to create a new array from it. Learning about arrays and the difference between declaring arrays using let and const keywords is an important lesson in JavaScript programming. While let and const are ES6 features that are newer, it is still vital for you to know how they work so you can create code that is optimal. Make sure to learn about arrays with let and const keywords and how they work before moving on.
