摩卡咖啡描述“意外的字符串错误”

Question

I am writing the below test cases using Mocha in node.js. Please find the below code :

describe('Car', function() {

it('can park?',function()

{ const car = new Car(); assert.equal(car.park(),'stopped'); }); });

I am running this using following command :

npm run test

It populates following error :

> inbox@1.0.0 test /Users/abc/test/
> mocha

/Users/abc/test/Inbox.test.js:18
describe('Car', function() {
     ^^^^^

SyntaxError: Unexpected string

Can you please help me, what i am doing wrong here?

Note : package.json is also updated with mocha in scripts field.

Answer 1

I know i am answering to my own question but its more like recording it for others.

Just Use following statement in your code at top or before describe statements

"use strict";
