I am running below javascript, but the bumper $($the object$)$ does not move$/$initiate at all and there is no colour lines.

function setTailColor$($color$)\{$

$//$ Implementation to set the tail color $($e$.$g$.,$ change the color of a variable or object property$)$

$\}$

function moveToTile$($x$,$ y$)\{$

$//$ Implementation to move Bumper to the specified tile

$\}$

function exploreAndMapMaze$()\{$

setTailColor$("$lightblue$")$;

move$()$;

turnLeft$()$;

move$()$;

returnToStart$()$;

$\}$

function returnToStart$()\{$

setTailColor$("$red$")$;

turnLeft$()$;

turnLeft$()$;

move$()$;

raceToMiddle$()$;

$\}$

function raceToMiddle$()\{$

setTailColor$("$green$")$;

let goalTileX $=5$;

let goalTileY $=5$;

if $($goalTileX $>$ getCurrentTileX$())\{$

turnRight$()$;

move$()$;

$\}$ else if $($goalTileX $<$ getCurrentTileX$())\{$

turnLeft$()$;

move$()$;

$\}$

if $($goalTileY $>$ getCurrentTileY$())\{$

turnDown$()$;

move$()$;

$\}$ else if $($goalTileY $<$ getCurrentTileY$())\{$

turnUp$()$;

move$()$;

$\}$

$\}$
