I got a syntax error in my async function

To declare a function with the ES6 "fat-arrow", you have to do this:

//note the "const" before the function name
const likeTagsProcess = async (tags = []) => {
   //do whatever you want to do
}

You can find more information here:
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Functions/Arrow_functions

I added const: and it worked properly thank you guys.

` const : likeTagsProcess = async (tags = []) => {...}

`

It looks like likeTagsProcess is an object project and should be defined using { key: value }.

So you code should look like this

const someObject = {
  likeTagsProcess: async (tags = []) => {
    for (let tag of tags) {

      // Go to the hashtag page
      await instagram.page.goto(TAG_URL(tag), {
        waitUntil: 'networkidle2'
      });

      await instagram.page.waitFor(1000);

      let posts = await instagram.page.$$('article > div:nth-child(3) img[decoding="auto"]');

      for (let i = 0; i < 3; i++) {

        let post = posts[i];

        // Click on the post
        await post.click();

        // Wait for the modal to appear
        await instagram.page.waitFor('span[id="react-root"][arria-hidden="true"]');
        await instagram.page.waitFor(1000);


        // Liking Posts
        let isLikable = await instagram.page.$('span[aria-label="Like"]');

        if (isLikable) {

          // Clicking Like
          await instagram.page.click('span[aria-label="Like"]');

        }

        await instagram.page.waitFor(2500);

        // Close the modal 


        await instagram.page.click("body > div._2dDPU.CkGkG > div.Igw0E.IwRSH.eGOV_._4EzTm.BI4qX.qJPeX.fm1AK.TxciK.yiMZG > button > svg");
        await instagram.page.waitFor(1000);
      }

      await instagram.page.waitFor(10000);

    }
  }
}
