Arrow functions allow you to have an implicit return – values are returned without having to use the return keyword. With a loop we can automate and repeat a block of code however many times we want it to run, even indefinitely. I personally prefer single quotes all the time, and use double quotes only in HTML to define attributes. You can use the following operators to compare two numbers, or two strings. After assignment and math operators, the third set of operators I want to introduce is conditional operators.
This is because arrow functions are not bound to the object. And like regular functions, we can only return one value. Template literals are also great because they provide an easy way to interpolate variables and expressions into strings. The conditional checks the expression you pass to it for a true or false value.
- They are a way to define a common pattern for multiple objects.

- In this SoloLearn course, you will learn about conditions, loops, functions, objects, arrays, the DOM, and events.
- That’s why we’ve developed a separate flashcards app where you can reinforce the new concepts that you learned using spaced repetition.
This course also uses exercises to cement concepts, but we dive much deeper into how these things work, gotchas, best practices, tooling and more. As always, absolutely no use of foo, bar, baz or any other confusing programming conventions. I’m not going to make you sit through me reading the docs of every single method available — that is boring and you can do that as you need it. Frustration, abandonment and rage quits all stem from trying to use something when we don’t understand how things work.
