(Will the database still work when thousands of users are simultaneously trying to retrieve their passwords?)

This is because they have things like security and scalability in mind.Ī coder’s responsibility, on the other hand, will involve writing code that results in a certain user story being fulfilled.įor example, if the user story is that Alex should be able to receive an email when they click the “forgot password” button, a coder will write a program to help Alex retrieve their password.Ī programmer will need to take a factor like scalability into consideration when choosing the database to be used to store Alex’s data. In addition to writing code, a programmer is also involved in high-level problem-solving.įor example, a programmer might advise on the technologies that should be used in a project. The two terms, however, differ in terms of their scope. This is because both involve writing programs. In the previous section, we saw that the terms “coding” and “programming” can be used interchangeably.

What’s the difference between coding and programming? But is that correct? Let’s compare the two terms in the next section. “Machine code” is information stored in zeros and ones (binary digits).Ī person who writes programs is called a coder or programmer.Ĭoding and programming are usually used interchangeably. Some “computer languages” include Python, Java, C, C++, and JavaScript.Ĭomputers use compilers and interpreters to convert programs into what’s known as machine-readable code. A human needs to learn “computer language” (commonly known as programming languages) to write programs that the computer can understand. The computer is then able to read the instructions (called “programs”) and do what you have asked it to do.Ĭomputer language is different from human language. So, what is coding? Coding can be defined as writing instructions for computers and other hardware. What’s the difference between coding and programming?Īre you ready to start discovering all about coding?

How does it really work “behind the scenes”? What kind of jobs can you get with coding skills? And where would you get started with learning how to code? You’ve probably come across the term “coding,” and have heard that it’s a great place from which to launch your tech career.īut what is coding really? Is it the same as programming? Where are you likely to use code? Is it that important, or is it over-glorified? We appreciate donations of all sizes, large and small.Have you ever wondered how many people it takes to build all the technology around us? Better still, curious about the behind-the-scenes of how the tech actually works?

ScratchJr is a collaboration between the Lifelong Kindergarten research group at the MIT Media Lab, the Developmental Technologies research group at Tufts University, and the Playful Invention Company. The ScratchJr interface and programming language were redesigned to make them appropriate for younger children’s cognitive, personal, social, and emotional development. ScratchJr was inspired by the popular Scratch programming language (), used by millions of people (ages 8 and up) around the world. With ScratchJr, children don’t just learn to code, they code to learn. They also use math and language in a meaningful and motivating context, supporting the development of early-childhood numeracy and literacy.

In the process, children learn to solve problems, design projects, and express themselves creatively on the computer. With ScratchJr, young children (ages 5-7) learn important new skills as they program their own interactive stories and games.īy snapping together graphical programming blocks, children can make characters move, jump, dance, and sing.
