--description--
Functions are ideal for reusable logic. When a function itself needs to reuse logic, you can declare a nested function to handle that logic. Here is an example of a nested function:
const outer = () => {
const inner = () => {
};
};
Declare a nested createLabel function using arrow syntax. It should take a name parameter.
--hints--
You should declare a createLabel variable in your onload function.
assert.match(code, /window\.onload\s*=\s*\(\s*\)\s*=>\s*\{\s*(?:const\s+container\s*=\s*document\.getElementById\(\s*('|"|`)container\1\s*\)\s*;?)?\s*(?:let|var|const)\s+createLabel/);
Your createLabel variable should be declared after your container variable.
assert.match(code, /window\.onload\s*=\s*\(\s*\)\s*=>\s*\{\s*const\s+container\s*=\s*document\.getElementById\(\s*('|"|`)container\1\s*\)\s*;?\s*(?:let|var|const)\s+createLabel/);
Your createLabel variable should be declared with const.
assert.match(code, /window\.onload\s*=\s*\(\s*\)\s*=>\s*\{\s*const\s+container\s*=\s*document\.getElementById\(\s*('|"|`)container\1\s*\)\s*;?\s*const\s+createLabel/);
Your createLabel variable should be an arrow function.
assert.match(code, /window\.onload\s*=\s*\(\s*\)\s*=>\s*\{\s*const\s+container\s*=\s*document\.getElementById\(\s*('|"|`)container\1\s*\)\s*;?\s*const\s+createLabel\s*=\s*(\(.*\)|[^\s()]+)\s*=>/);
Your createLabel function should have a name parameter.
assert.match(code, /window\.onload\s*=\s*\(\s*\)\s*=>\s*\{\s*const\s+container\s*=\s*document\.getElementById\(\s*('|"|`)container\1\s*\)\s*;?\s*const\s+createLabel\s*=\s*(\(\s*name\s*\)|name)\s*=>/);
Your createLabel function should be empty.
assert.match(code, /window\.onload\s*=\s*\(\s*\)\s*=>\s*\{\s*const\s+container\s*=\s*document\.getElementById\(\s*('|"|`)container\1\s*\)\s*;?\s*const\s+createLabel\s*=\s*(\(\s*name\s*\)|name)\s*=>\s*\{\s*\}/);
