19 #1825DaysOfCode Arrays are indexes by number Objects are indexes by name #fundamentalsJS
15 #1825DaysOfCode REDUCE THE PROBLEM TECHNIQUE V.Anton Spraul. For example,suppose you’re asked to write a program that reads ten numbers and figures out which number is the third highest. If you are stuck, you should reduce the problem to something simpler. #fundamentalsJS
9 #1825DaysOfCode HTML represents initial page content, and the DOM represents current page content. When JavaScript adds, removes, or edits nodes, the DOM becomes different than the HTML. #fundamentalsJS
20 #1825DaysOfCode Test Driven Development(TDD) Its refers to the practice of writing automated tests that describe how your code should work (supplies the expected output) before you actually write a code. #fundamentalsJS
24 #1825DaysOfCode Branches in git allow your repository to hold multiple alternate reality versions of your files at the same time. When you make commits on a specific branch those changes only exist on that branch and don’t affect any other branch. #fundamentalsJS
14 #1825DaysOfCode Arrow Functions => let func = (arg1, ,argN) => expr This creates a function func that accepts arguments argN, then evaluates the expression expr on the right side with their use and returns its result. #fundamentalsJS
12 #1825DaysOfCode A parameter is the variable listed inside the parentheses in the function declaration (it’s a declaration time term). An argument is the value that is passed to the function when it is called(its a call time term). #fundamentalsJS
11 #1825DaysOfCode Anonymous function/function expression Has no name,you will often see its when a function expects to receive another function as a parameter. In this case the function parameter is often passed as a anonymous function. #fundamentalsJS
18 #1825DaysOfCode Node.js Provides a interactive console which lets you debug/test and edit small snippets of your javascript code right in your terminal without opening the browser every time. Type: ^node^ in terminal to run it, ^exit^ to quit the console. #fundamentalsJS
13 #1825DaysOfCode Naming a Function Functions are actions So their name is usually a verb. It should be brief, as accurate as possible and describe what the function does. It is a widespread practice to start a function with a verbal prefix. #fundamentalsJS
16 #1825DaysOfCode Pseudocode Is useful to learn because it focuses on the building block concepts of programming languages. Once you’ve nailed the logic of coding, the rest is just filling in your pseudocode with the syntax of a particular programming language. #fundamentalsJS
It is always easier to understand a function which gets parameters, works with them and returns a result than a function which gets no parameters, but modifies outer variables as a side-effect. #fundamentalsJS
A function should do exactly what is suggested by its name, no more. Two independent actions usually deserve two functions, even if they are usually called together. In that case we can make a 3rd function that calls those two. #fundamentalsJS
A separate function is not only easier to test and debug - its very existence is a great comment! Functions can be created even if we don’t intend to reuse them. They structure the code and make it readable. Sometimes people refer to such code as self-describing. #fundamentalsJS
