How to fix babel Unexpected reserved word 'interface' error

Question

I want to transpile pure js code in gulp using babel. But there is a variable "interface" in my code. For example

function func(interface) {
    console.log(interface)
}

How can I fix this?

Packages versions

"@babel/core": "^7.14.6",
"@babel/preset-env": "^7.14.5",
"gulp": "^4.0.2",
"gulp-babel": "^8.0.0",

My gulp task

function transpileJs() {
    return gulp.src(['folder/**/*.js'])
        .pipe(babel({
             presets: ['@babel/preset-env'],
        }))
        .pipe(gulp.dest('folder/dest/'));
}

Error

Thanks for the help

Answer 1

The word "interface" is a reserved in "strict mode". That's why you cannot use it as an identifier to declare any variable or function parameter.

Rename you function parameter and the problem will go away.
