I set it up like this: .babelrc: { "presets": ["es2015", "es2017"] } gulpfile: gulp.task('default', function() { return gulp.src(['src/**/*.js', '!src/**/3rd/*']) .pipe(babel()) .pipe(gulp.dest('dist')); }); However this seems to be compiling to es5 which is not fully supported in Safari. Is there a way to set target? So it can compile to ES3? 回答1: No, Babel does not support transpiling to ES3. Your options are: Compile to ES5 and then use ES5 shim . Use a different transpiler.

Since the GitHub repository linked above says it's a stage 3 proposal, I assumed it would be part of babel-preset-stage-3, but it seems not. Is there any Babel preset (or even plugin?) that lets me use Object.entries today? 回答1: Using babel , installing babel-preset-es2017 babel-plugin-transform-runtime gives support for Object
