YAML is a way to store information computers use that’s also easy for humans to read. Instead of tags (like in XML) you just use spaces! It might sound like Camel, but it’s YAML! #precoding #prekcoding #edtech #coding #codingforkids #codingbasics #codingnewbie
After we learned in class they wanted to try it on their own. #prekcoding #HourOfCode2020 #Speaklife #CJ_lions_CJES
This week @PKAcademyWAve students listened to Rosie's Walk, observed the position of objects, gave they give each other directions, and build their knowledge playing #Boxisland #Prekcoding @NEISDPreK #theNEISDway #neisdlibrary
In programming, when something is “undefined” it means it doesn’t have a value yet. If you don’t know what that value should be, you can assign it to NULL first! #precoding #prekcoding #edtech #coding #codingforkids #codingbasics #codingnewbie
Strings are sets of characters stored together in a computer program. You can use strings to have a “conversation” within your code! #precoding #prekcoding #coding #code #codingforkids #codingbasics #codingnewbie
“Return” is a statement that tells a function it’s finished. Return can also bring back a value once the function is completed. Just like getting a gumball back from a machine! #precoding #prekcoding #edtech #coding #codingforkids #codingbasics #codingnewbie
A queue is a data structure in which elements are removed in the same order they were entered. We call that FIFO “First in, first out”. Just like waiting in a line, first come first served! #precoding #prekcoding #edtech #coding #codingforkids #codingbasics #codingnewbie
A pointer, in programming, is a small reference to larger data, like an address! You use an address to reference where someone lives. #precoding #prekcoding #edtech #coding #codingforkids #codingbasics #codingnewbie
An object is used in programming to store data and functions that you can reuse later. It’s like having a toolbox that you can carry around and pull tools out of! #precoding #prekcoding #edtech #coding #codingforkids #codingbasics #codingnewbie
Null is used when you want to show that a value does not exist yet. When we have a variable and don’t know what it is, it can first be set to null! #precoding #prekcoding #edtech #coding #codingforkids #codingbasics #codingnewbie
A megabyte is a unit of measurement (like kilobyte and gigabyte) that represents one million bytes. Megabytes are used for things like music files! #precoding #prekcoding #edtech #coding #codingforkids #codingbasics #codingnewbie
Loops are fundamental programming concepts. They tell a program to repeat an action until a certain condition is met. This keeps us from having to write the same thing over and over! #precoding #prekcoding #edtech #codingforkids #codingbasics #codingnewbie
A kilobyte represents a unit of data! Kilobytes are made of 1024 bytes. #precoding #prekcoding #edtech #coding #codingforkids #codingbasics #codingnewbie
JSON is a way to organize data shared between programs. It's also how information is sent to a website or mobile app! It’s also an acronym that means: JavaScript Object Notation. #precoding #prekcoding #edtech #codingforkids #codingbasics #codingnewbie
An integer is any whole, non-decimal number that can be positive, negative, or zero. Sometimes we need 1, 2, or 3 cups of coffee, and those numbers are all integers! #precoding #prekcoding #edtech #codingforkids #codingbasics #codingnewbie
HTML is a special kind of computer language that builds websites. It tells a site how to show text, colors, and images. It looks like this! <html> <head></head> <body>Hi!</body> </html> #precoding #prekcoding #edtech #codingforkids #codingbasics #codingnewbie
A gigabyte is a unit of measurement that represents 1 billion bytes! Gigabytes are used for storing things that take up large amounts of data, like a movie. #precoding #prekcoding #edtech #coding #codingforkids #codingbasics #codingnewbie
A function is code with a name that you can reuse, like reusing a favorite tote bag! Once you have a function, you reference it in different places in your code so you don't have to repeat yourself. #precoding #prekcoding #edtech #codingforkids #codingbasics #codingnewbie
Enum is short for "enumeration". It's a data type that has to be one of a set of values, like a choice! If you can pick either a blue or yellow balloon, then the balloon’s color would be an enum! #precoding #prekcoding #edtech #codingforkids #codingbasics #codingnewbie
Writing code can be tricky and it’s easy to make mistakes! When you have to go through and fix them, we call that “debugging”. Never feel bad if you find bugs in your code, it happens to everyone! #precoding #prekcoding #edtech #codingforkids #codingbasics #codingnewbie
