Re-creating the lodash library - project

Projects
1

I am trying to complete the final project from “Introduction to JavaScript”. This project is called: RE-CREATING THE LODASH LIBRARY.
https://www.codecademy.com/paths/web-development/tracks/web-dev-js-arrays-loops-objects/modules/pjs-javascript-capstone/projects/lodash

I am stuck at item 6. In this project there is no “hint” or video to help, which make it very difficult.

After running node test/clamp.js on the Terminal, I am getting an error saying that there is a syntax error in line 13 => module.exports = _;

But this is a code that CodeCademy commented not to modify. What should I do?

// Do not write or modify code below this line.
module.exports = _;

Hey man, so I was stuck for a few minutes on this until I realized I hadn’t saved my code. I know it might seem silly but make sure that you are saving your code before running the test. If your code looks like what I have below then it should pass the test!

const _ = {
  clamp(number, lower, upper) {
    const lowerClampedValue = Math.max(number, lower);
    const clampedValue = Math.min(lowerClampedValue, upper);
    return clampedValue;
  }
};




// Do not write or modify code below this line.
module.exports = _ ;

Hi. I’ve saved the code and the problem persists. My code is the same as yours. Take a look at the attached image, please, and see if you can find what might be wrong.

Hey man it looks like you’re missing a closing bracket thats all. you have this:
let _ = { clamp(number, lower, upper) { let lowerClampedValue = Math.max(number, lower); let clampedValue = Math.min(lowerClampedValue, upper); return clampedValue; }

After return clampedValue you should something like this

    return clampedValue;
  }
};

Also I would refrain from using let to set “_” since it shouldn’t be changed later on. Your code will work but it’s not wise to use “let” everywhere. Remember use “const” when a variable’s value should not be changed and only use “var” or “let” when you know your variable may be changing later on.

Wow, that’s true. Now it’s working. Thank you a lot for all your help. It’s amazing how I didn’t see this.
