Error handling

Browser runtime: loading…

Use errors for exceptional paths, rescue them around a block, or put a rescue clause directly inside a method body. Each runnable snippet uses the same WASM engine as the playground.

Errors and rescue

Raise errors with raise. Use begin / rescue, or place a rescue clause directly inside a method body when the whole method has one fallback path.

def safe_divide(a: Int, b: Int) -> Int {
  a / b
rescue e
  print "cannot divide: #{e}"
  0
}

print safe_divide(10, 2)
print safe_divide(10, 0)
