Reference: JavaScript Tutorial: Comparison Operators. The == operator will compare for equality after doing any necessary type conversions. The === operator will not do the conversion, so if two values are not the same type === will simply return false. Both are equally quick.
Basic meaning and syntax. Both keywords can be used in the declaration of objects as well as functions. The basic difference when applied to objects is this: const declares an object as constant. This implies a guarantee that once initialized, the value of that object won't change, and the compiler can make use of this fact for optimizations.
Semantic: The meaning or purpose of a thing. "Create a constant, name it after the meaning, and replace the number with it." -- Martin Fowler. First, magic numbers are not just numbers. Any basic value can be "magic". Basic values are manifest entities such as integers, reals, doubles, floats, dates, strings, booleans, characters, and so on.
In linguistics, to divide language into small components that can be analyzed. For example, parsing this sentence would involve dividing it into words and phrases and identifying the type of each component (e.g.,verb, adjective, or noun). Parsing is a very important part of many computer science disciplines.
Provide space the same as a regular space. Correct syntax : (must add a semi-colon at the end) is a character entity for a non-breaking space. You can use it either inside the container tag or just after closing the tag: <!--Inside container tag-->. <p>Text Text</p>. <!--After closing the tag-->.
Floats and integers are comparable as they are numbers but are usually not equal to each other except when the float is basically the integer but with .0 added to the end. When using ==, if the two items are the same, it will return True. Otherwise, it will return False. You can use = to assign values to variables.
2. First-cut Techniques means the approach that comes to your mind first time you see a problem. For example, in this graph, the edges represent path from one node to other and the values represent cost of taking the path. Let's say, you put a baby on node 1 and tell it to go to node 3 using a path that costs minimum.
Just to get it right: URI = Tells you in which hotel you should go to sleep. URL = Tells you in which room in what hotel you should go to sleep. So URL is a lot more specific, it points to a final destination. The thing you want. While URI is something strange.
keyword argument is all of the "unknown/unexpected" named argument that being passed by name. for example, let's define a function with one argument
8. The backslash \ is a character, just like the letter A, the comma ,, and the number 4. In some programming languages, notably C and its descendants (and maybe ancestors), it is used inside a string or character literal to escape other characters. For instance, '\a' represents the bell character, and will produce a beep from the computer if ...
