Where is the error in the GULP build?

Question

C++ / C#

node -v v11.9.0
gulp -v
[23:31:30] CLI version 2.0.1
[23:31:30] Local version 4.0.0

Does not work correctly, no changes in css when saving sass

const gulp = require('gulp');
const sass = require('gulp-sass');
const plumber = require('gulp-plumber');
const autoprefixer = require('gulp-autoprefixer');
const browserSync = require("browser-sync").create();

function style() {
    return (
        gulp.src("./src/sass/style.sass")
            .pipe(plumber())
            .pipe(sass()).on("error", sass.logError)
            .pipe(autoprefixer())
            .pipe(gulp.dest("./src/css/style.css"))
            .pipe(browserSync.stream())
    );
}

function reload() {
    browserSync.reload();
}
 
function watch() {
    browserSync.init({
        server: {
            baseDir: "./src"
        }
    });
    gulp.watch("src/sass/*.sass").on('change', browserSync.reload);
    gulp.watch("src/*.html").on('change', browserSync.reload);
}

exports.style = style;
exports.reload = reload;
exports.watch = watch;

Answer 1

The first argument in your function, as I understand it, implies the length of the word?
If so, then the sizeof of the string does not depend on its actual length.
In the inner loop, when you try to swap words, the j variable does not change.

Answer 2

Addstyle

gulp.watch("src/sass/*.sass", style).on('change', browserSync.reload);
