Vue.js encountered an unexpected strict mode reserved word error that was not caught

I have initialized a Vue instance

var app = new Vue(
{...}
)

Additionally, I have defined a class named CustomTooltip

class CustomTooltip {

    constructor(array_data,vue_instance) {
        this.tooltip_data = array_data;
        this.vue_instance = vue_instance

        console.log(app)

    }
}

While trying to utilize the 'app' instance within certain methods of the CustomTooltip class, I encountered an error message stating

Uncaught SyntaxError: Unexpected strict mode reserved word
. This issue was resolved by passing the Vue instance to the constructor, although it now requires passing the app variable each time a new CustomTooltip instance is created.

Can anyone explain why this error is occurring? How can I resolve this issue effectively? Should I consider a different approach?

Answer №1

Do you work with TypeScript? In that case, remember that the keyword interface is reserved for declaring interfaces. You can learn more about it here: https://www.typescriptlang.org/docs/handbook/interfaces.html

To solve the issue, consider renaming your variable to something like myInterface. This simple change should address the issue.

If TypeScript is not involved, encountering the error might come as a surprise.
