--description--

You can easily <dfn>decrement</dfn> or decrease a variable by one with the -- operator.

i--;

is the equivalent of

i = i - 1;

Note: The entire line becomes i--;, eliminating the need for the equal sign.

--instructions--

Change the code to use the -- operator on myVar.

--hints--

myVar should equal 10.

assert(myVar === 10);

myVar = myVar - 1; should be changed.

assert(!__helpers.removeJSComments(code).match(/myVar\s*=\s*myVar\s*[-]\s*1.*?;?/));

You should not assign myVar with 10.

assert(!__helpers.removeJSComments(code).match(/myVar\s*=\s*10.*?;?/));

You should use the -- operator on myVar.

assert(/[-]{2}\s*myVar|myVar\s*[-]{2}/.test(__helpers.removeJSComments(code)));

You should not change code above the specified comment.

assert(/let myVar = 11;/.test(__helpers.removeJSComments(code)));

--seed--

--seed-contents--

let myVar = 11;

// Only change code below this line
myVar = myVar - 1;

--solutions--

let myVar = 11;
myVar--;
