Tish - Native Performance, Familiar Syntax

Conditionals

if (cond) stmt
if (cond) stmt else stmt

Loops

while (cond) stmt
do stmt while (cond)
 
for (init; cond; update) stmt
for (let x of arr) stmt
for (const x of arr) stmt

C-style for: init, cond, update are optional.
for-of: Iterate over arrays and strings. Use let for mutable binding, const for immutable.

Switch

switch (expr) {
    case val1: stmt...
    case val2: stmt...
    default: stmt
}

Return, break, continue

return expr
break
continue

Error handling

throw expr
try stmt catch (e) stmt

typeof and void

typeof expr   // returns "number", "string", "boolean", "null", "object", "function"
void expr     // evaluates expr, returns null

typeof null returns "null" in Tish (unlike JavaScript, where typeof null === "object"). Since Tish has no undefined, it uses null as the absence-of-value type, and typeof reflects that.

Blocks

Blocks use braces { } or indentation:

if (x > 0) {
    console.log("positive")
} else {
    console.log("non-positive")
}
 
if (x > 0)
    console.log("positive")
else
    console.log("non-positive")
