Z^3 Language Documentation
Assignment Operators
z^3 allows assigning values to the left as well as to the right using <== and ==> operators. This allows better expressivity for more logical thinking.
a <== 23; 23 ==> a;
a <== 23; is equivalent to a=23; and both notations are equivalent in z^3.
:= : Quick Function Creation Operator
The quick function creation operator in z^3 ( := ) is similar to the => operator in Javascript. However, the advantage of := operator is that the parameters are not named explicitly (and is autodetected). For example to define a function such as v=u+a*t, v:=u+a*t is sufficient, and the parameters u, a and t are auto detected.
Any variable names with lowercase (such as ab, cde, etc) with less than 3 characters in length, is considered to be a local variable. All other names (including any longer variable lowercase names) are checked to see if there is a similar name already in a higher or global scope, and in which case, will not be treated as a local variable.
The => function definition operator in normal Javascript, differs slightly. Hence to define a function such as v=u+a*t, in Javascript (as well as z^3), it would require us to indicate it as v=(u,a,t)=>u+a*t;
The := operator in z^3 hence allows avoiding explicitly repeating the parameter names again in the argument list and function body.
v:=u+a*t and v=(u,a,t)=>u+a*t; both are equivalent to
function v(u,a,t)
{
return(u+a*t)
}

Logical Statements
If Statements
a=3;
(a<0)::{"whatever"},
{
!(a>4)::
{"whateverelse"},
{"whateverelseleft"}
}
(a>4)::
{"whateverelse"},
{"whateverelseleft"}
Switch Statements
Apart from the conventional Javascript switch statement syntax, z^3 enhances language simplicity with a new style.
The new z^3 switch statements syntax is as follows.
discriminant:::
{
x, y::
/*statements to be executed if x or y is true*/
/*Break is automatically added. */
/*Simply add an empty statement using a simple extra semicolon (;)) */
,
z::
/*statements to be executed if z is true*/
,
default::
}
For example,
b=0;
c=343;
fruits="mango";
fruits:::
{
"apple","tomato"::
b++;
c=3.4;
,
"mango"::
b=34905;
,
default::
b=45.6;
}
[b,c];
switch(a)
{
case b:
case c:
break;
default:
break;
}
Loops
a=1;
do
{
a++
}
until(a>20); // do while(!condition)
a; // here this will be 21, since !condition is checked like a do while loop.
a=11;
b=45;
because(a<b)
{
a++
OUTPUT(a)
}
a=11;
do
{
a++
}
unless(a==11);
a;
Function Declarations
function y(x)
{
∵(x<345)
{
∴(x+3434)
}
∵(x>345)
{
∴(x-3434)
}
}
y(13);
The letter Ƒ can also be used instead of the full term function.
Ƒ y(x)
{
∵(x<345)
{
∴(x+3434)
}
∵(x>345)
{
∴(x-3434)
}
}
y(13);
Existential Quantification
a=1..100;
∀a("x<810")
∃a("x<810")
∄a("x<810")
a=1..100;
[∀a("x<810"),∃a("x<810"),∄a("x<810")]
a=1..100;
[∀a("x<810"),∃a("x<810"),(!∄a("x<0"))]
a=1..100;
b= ∀a("y*2<200");
b.result
a=1..100;
b= ∀a("y*2<=50");
a.pick(b.result)
//make a pick operator based on a similar array of true false. or non-existant to get the values out.
//PICK
a=1..100;
b= ∀a("y*2<50");
a.pick(b.result)
