        .pipe(gulp.dest('polyfills.js'));
});

Or:

var gulp = require('gulp');
var polyfiller = require('gulp-polyfiller');
 
gulp.task('default', function () {
    gulp.src("*.js")
        // push polyfills file after all scripts
        .pipe(polyfiller(['Promise', 'Fetch']))
        // run then any tasks on your scripts
        .pipe(concat())
