sourcemap:true, ??? sourcemaps.write()

Question

which codes snippet should I use ?

sourcemap:true,

gulp.task('typescript-options', function() {
    gulp.src('./TypeScript/**/*.ts')
        .pipe(tsc({
            sourcemap:true,
            target:'ES5'
        }))
        .pipe(gulp.dest('./build/TypeScript'));
});

sourcemaps.write()

gulp.task('typescript-options', function() {
    gulp.src('./TypeScript/**/*.ts')
        .pipe(tsc({
            sourcemaps.write(),
            target:'ES5'
        }))
        .pipe(gulp.dest('./build/TypeScript'));
});
