Today, I decided to take my first steps into programming by looking at the first 2 lessons in Lifehacker’s Night School.
The “hello world!” statement is the most famous first steps for programmers and it will be the same for me as I take my first steps into learning javascript for the first time.
In these two lessons, I was re-introduced into the familiar terms; strings, booleans, and variables.
Strings are alpha-numeric characters that are allowed in programming and are contained within quotation marks.
Booleans, I have been reminded that they are true or false statements that act like on and off switches. For example, you can ask your program “is this video playing?” If it was, your program would report back a true statement and if it wasn’t, you’d be returned with a big fat false.
In my first program, I confidently walked through my “Hello World!” statement after being introduced how to start strings in javascript. (each programming language is different)
After lesson 1, lesson 2 introduces the user into how to do variable statements in javascript. I re-learned in javascript how to declare a variables. I followed the tutorial and learned how to make a programming telling the user how many fruits the user ate. Advancing further, the tutorial teaches how programs that you use to write programming code can do calculations. This is demonstrated by stating a variable and then adding addition or subtraction signs in-between them to denote that their numerical values should be added or subtracted.
