Some features:

• Ruby-like syntax, terse lambdas that look like regular control statements.
• Everything is an object.
• Integrated package manager.

Jaguar is a small app that wirelessly connects to an ESP32 and can load and live-reload Toit programs. This is opposed to something like connecting the device via USB and re-installing the program every time you make a change.

Example (github.com/toitlang/toit/blob/master/…/scan.toit, see the GitHub link for syntax highlighting):

// This example illustrates how to scan for WiFi access points.

import net.wifi

SCAN-CHANNELS := #[1, 2, 3, 4, 5, 6, 7]

main:
  access-points := wifi.scan
      SCAN-CHANNELS
      --period-per-channel-ms=120
  if access-points.size == 0:
    print "Scan done, but no APs found"
    return

  print """

      $(%-6s "RSSI") $(%-8s "Channel") \
      $(%-8s "Author")\n"""

  access-points.do: | ap/wifi.AccessPoint |
    print """

        $(%-6s ap.rssi) $(%-8s ap.channel) \
        $(%-8s ap.authmode-name)"""
