In JavaScript, you can add items to an array in a number of ways, like initializing the array with an item, pushing an item into the array, combining arrays, etc. Here we'll see how you can push a JavaScript object into an array. To achieve this, we'll use the push method. let ...
This solution works fine, but thearray.pushmethod mutates thedishobject. In other words, the originaldishobject changes, which is considered a bad practice. A mutation is a side effect: the fewer things that change in a program, the less there is to keep track of, which results in a si...
