Error due to "constrain" not being defined in the current scope

[nopivnick]

🌸 p5.js says: There's an error due to "constrain" not being defined in the current scope (on line 98 in display.js [http://localhost:3000/scripts/display.js:98:3]).

If you have defined it in your code, you should check its scope, spelling, and letter-casing (JavaScript is case-sensitive). For more:

p5@1.1.9.js:46741 Did you just try to use p5.js's constrain() function? If so, you may want to move it into your sketch's setup() function.
