--description--
When defining functions within objects in ES5, we have to use the keyword function
as follows:
const person = {
name: "Taylor",
sayHello: function() {
return `Hello! My name is ${this.name}.`;
}
};
With ES6, you can remove the function
keyword and colon altogether when defining functions in objects. Here's an example of this syntax:
const person = {
name: "Taylor",
sayHello() {
return `Hello! My name is ${this.name}.`;
}
};
--instructions--
Refactor the function setGear
inside the object bicycle
to use the shorthand syntax described above.
--hints--
Traditional function expression should not be used.
assert(!__helpers.removeJSComments(code).match(/function/));
setGear
should be a declarative function.
assert(
typeof bicycle.setGear === 'function' && __helpers.removeJSComments(code).match(/setGear\s*\(.+\)\s*\{/)
);
bicycle.setGear(48)
should change the gear
value to 48.
bicycle.setGear(48);
assert(bicycle.gear === 48);
--seed--
--seed-contents--
// Only change code below this line
const bicycle = {
gear: 2,
setGear: function(newGear) {
this.gear = newGear;
}
};
// Only change code above this line
bicycle.setGear(3);
console.log(bicycle.gear);
--solutions--
const bicycle = {
gear: 2,
// setGear: function(newGear) {
setGear(newGear) {
this.gear = newGear;
}
};
bicycle.setGear(3);
