Syntax is a language.
Learn it with your hands,
not your eyes.

SyntaxStreak turns brackets, semicolons, and boilerplate into a daily habit — three fast drills, one streak to protect.

Three drills, one muscle

SPRINT

Type it until it's automatic

Race the clock through real JS and C++ patterns — brackets, arrows, templates — until your fingers stop hunting for keys.

SPOT-THE-BUG

Train your eye for what's broken

One hidden syntax error per snippet. Click the line. See why it breaks. Stop losing an hour to a missing brace.

SCRAMBLE

Rebuild the logic, in order

Lines shuffled, structure scrambled. Put a real function back together and internalize how the pieces actually flow.
