Importing

Ipade ko ni atilẹyin wọle gbólóhùn, nitorina awọn ti atijọ beere iṣẹ nilo lati wa ni lo nigba ti akowọle.

Nibi ti a gbe robot.js (akọsilẹ: .JS le optionally wa ni osi jade ni beere iṣẹ) and assign it to an object that we can name anything. We name it robot. Our robot object now holds our exported modules from robot.js

A le lo o bi wọnyi…

const robot = beere('./robot')


robot.sayHello()

console.log(robot.hello)

console.log(robot.greetings.french)

Ranti lati lo awọn ohun orukọ ti o ti yàn lori akọkọ ila nigba lilo rẹ module ayípadà, iṣẹ tabi ohun.

akọsilẹ: Browsers do not support the require statement. Therefore you cannot use the require import module function with browsers without using a transpiler such as Babel or a bundler such as Browserify.
