| 56533eb9ac21ba0edf2244b0 | Compound Assignment With Augmented Subtraction | 1 | 16660 | compound-assignment-with-augmented-subtraction |
--description--
Like the += operator, -= subtracts a number from a variable.
myVar = myVar - 5;
will subtract 5 from myVar. This can be rewritten as:
myVar -= 5;
--instructions--
Convert the assignments for a, b, and c to use the -= operator.
--hints--
a should equal 5.
assert(a === 5);
b should equal -6.
assert(b === -6);
c should equal 2.
assert(c === 2);
You should use the -= operator for each variable.
assert(__helpers.removeJSComments(code).match(/-=/g).length === 3);
You should not modify the code above the specified comment.
assert(
/let a = 11;/.test(__helpers.removeJSComments(code)) && /let b = 9;/.test(__helpers.removeJSComments(code)) && /let c = 3;/.test(__helpers.removeJSComments(code))
);
--seed--
--seed-contents--
let a = 11;
let b = 9;
let c = 3;
// Only change code below this line
a = a - 6;
b = b - 15;
c = c - 1;
--solutions--
let a = 11;
let b = 9;
let c = 3;
a -= 6;
b -= 15;
c -= 1;
