The terms JSON and object (and even JSON object ) are often used interchangeably when talking about a data structure, especially in AJAX-related contexts.
- What is the difference between both?
- Is a JSON a Javascript object or is it something else?
The next question: When should you use var, let and const in ECMA Script 6? It partially answers my question, but not completely.
Reading the accepted answer I have understood that:
letdeclare a local scope variableconstdeclare a constant inside a block (inside a function?)varI did not understand if it is local or globalAnd if it is not set
nada, what is the range? In another related question I read that when nothing is put, a global variable is being declared.
I'm a bit confused and would like to understand the exact scope of each form of variable declaration, in a simple answer if possible.
On the other hand, I don't know if this would be a topic for another question, but I don't quite understand what the concept of global would be in Javascript . Current DOM tab? All open tabs? All open browsers and tabs?
From a String, "123-654321", what I want is to split it into two Strings:
string1=123
string2=654321
In the code I see many times x++in loops, but sometimes I find ++x.
Is there a difference between these two expressions?
In C#, what is the difference between Stringand string? (see capitals)
Example:
string s = "¡Hola mundo!";
String S = "¡Hola mundo!";
What are the rules of use for each? And what are the differences?
Original question: What's the difference between String and string?
