var add = func(a, b) {a + b}
- Calling:
add(2, 6)
- Creation:
- Built-In Functions:
- Printing to console:
print('Hello World!')
- Testing:
assert(x == 10, 'x is not 10')
- Printing to console:
- Exception handler:
var x = handler {10 / 0}
- Assert / in-peri.dot testing:
assert(x == 9, 'x is not equal to 9')
- Flow control:
- If statements:
if (x == 1) {var y = 3} elif (x == 2) {var y = 2} else {var y = 1}
- Switch statements:
switch (var x in a) {case (x == 10) {print('10')} else {print('Hmm...')}}
- For loops:
for (var i in [True, True, False]) {print(i)}
- While loops:
while (x < 100) {x = x + 1}
- If statements:
Coming Soon
- Improved repl
- Classes for general use:
var Test = class() {a = 'hello'}
Possible Features
- Formatted strings
'Hello World{suffix}'
- More operations:
- Add and assign
+=
- Subtract and assign
-=
etc.
