Php
Something 2 remember
Every day
Python Collections ♣ Dictionaries
D = dict()
D["one"] = "uno"
D.get("one") == "uno"
D = {"one": "uno", "2": "dos"}
for v in D.values():
print(v)
Java Basics ♣ Exceptions
Using throws, forces developer to try/catch
A method can throw multiple exceptions
MyClass
myMethod() throws Exception {}
try
catch (Exception e)
Php Variables ♣ Exists
Downsides of the way PHP handles variables Use !empty(), not isset if(isset($a) && $a != "") if(!empty($a)) // better
JS Fundamentals ♣ Hello World
Code can be inserted into HTML
Also, into an external file
<script>
alert("Hello World");
</script>
<script src="hello.js"></script>
