Variables and base types

Variables definition

You can define vars with any type (yet without checking).

var num = 1;               
int i, j = 3;
String str = "someString";

Exists possibility to define object's property:

num myProfile.age = 19;

Also you can mark definition with modificators:

const myProfile.age = 10;

list of modificators:

• const to define constant
• covert to define unenumerable property (not var)
• export to export var or property from module (read more)

Variables assignment

In ColaScript you can use follow syntax to reduce object filling:

String name = "Felix";
int age = 3;
String about = "Black'n'white sly cat.";
	
Object info = { name, age, about }; // { name: name, age: age, about: about }

Also you can use destructuring assignment:

int a = 2, b = 3;
		
[a, b] = [b, a];                                      // swap
{ name, age, about, friends : [firstFriend] } = info; // with object
[firstSkill, ..., lastSkill] = skills;                // with array

Boolean aliases

In ColaScript, like in CoffeScript, exists boolean aliases:

yes == true && on  == true;
no == false && off == false;	

Strings

ColaScript have strings templating! You can paste value of variable in strings:

console.log(`my login in twitter \@@twLogin`); // and yes, you can ` quotes

Also we can paste result of expression by this way:

console.log("length of my name @{ name.length }");

and this way:

console.log("first letter in my name is {{ name[0] }}");

It is still possible to use raw strings:

console.log(r"\n\r\t@raw");

Any string in ColaScript is multiline:

console.log("	
List1:
    - Write code
    - Drink tea
    - Watch Instagram
			
List2
    * Write code
    * Read Habrahabr
    * Listen music			
");

align goes by closing-quote.

RegExps

Modifer x skips whitespaces and new-line same as if you use multiline RegExp:

// White spaces with `x` modifier will be removed.
RegExp isUrl = /^(https?:\/\/)? ([\w\.]+) \.([a-z]{2,6}\.?) (\/[\w\.]*)*\/? $/x;

// If regexp contains `new-line` then `x` modifier will be added automatically 
isUrl = /
    ^
        (https?:\/\/)?
        ([\w\.]+)
        \.([a-z]{2,6}\.?)
        (\/[\w\.]*)*\/?
    $/;
