56533eb9ac21ba0edf2244ad | Decrement a Number with JavaScript | 1 | https://scrimba.com/c/cM2KeS2 | 17558 | decrement-a-number-with-javascript |
--description--
You can easily decrement 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(
/var\s*myVar\s*=\s*11;\s*\/*.*\s*([-]{2}\s*myVar|myVar\s*[-]{2});/.test(code)
);
You should use the --
operator on myVar
.
assert(/[-]{2}\s*myVar|myVar\s*[-]{2}/.test(code));
You should not change code above the specified comment.
assert(/var myVar = 11;/.test(code));
--seed--
--after-user-code--
(function(z){return 'myVar = ' + z;})(myVar);
--seed-contents--
var myVar = 11;
// Only change code below this line
myVar = myVar - 1;
--solutions--
var myVar = 11;
myVar--;
