Ember Installation Issue: SyntaxError: Use of const in strict mode

The error message "SyntaxError: Use of const in strict mode" indicates that you are trying to use the const keyword in a context where strict mode is enabled, but the code itself might be in a non-strict mode context. This can happen if you are using a newer version of JavaScript that supports const but the environment you are running the code in doesn't support strict mode.

Here's how you can address this issue:

1. Check Environment Compatibility:
   Verify that the version of JavaScript you are using is compatible with the environment where you are running your code. For example, if you are using a JavaScript engine that doesn't support ES6 features like const, you might encounter this error.

2. Enable Strict Mode:
   It's a good practice to enable strict mode for your JavaScript code. Strict mode helps catch common coding mistakes and makes your code more robust. To enable strict mode, add the following line to the top of your JavaScript file:

   javascriptCopy code
   'use strict';
   
   

   Make sure this line is the first line in your JavaScript file.

3. Check Ember Version:
   Ensure that you are using a version of Ember.js that is compatible with the JavaScript environment you are running. Newer versions of Ember.js might rely on ES6 features like const, so make sure you are using a version that matches your environment's capabilities.

4. Check Your Build Tooling:
   If you are using build tools like Babel or Webpack, make sure they are configured to transpile your code to a version of JavaScript that is compatible with your target environment.

5. Update Your Environment:
   If possible, consider updating your environment (browser, Node.js, etc.) to a version that supports modern JavaScript features.

6. Use var or let:
   If you are unable to enable strict mode or you are dealing with an environment that doesn't support const, consider using var or let instead.

Remember that the specific solution might depend on your code, environment, and the version of Ember.js you are using. It's also a good practice to consult the official Ember.js documentation or community forums for guidance on installation and compatibility issues.
