Mastering the art of combining various techniques in JavaScript simultaneously

My website features a search input field where users can search for specific courses by name using filtering and the includes() method. However, I am facing an issue where I need to apply three methods simultaneously: toLowerCase(), toUpperCase(), and trim().

GetFilteredCourses() {
  return this.courses.filter(course => {
    return course.title.toLowerCase().includes(this.searchTerm);
  });
},

It is essential to include both toLowerCase() and toUpperCase() in order to handle different cases during searches. Removing these methods would result in users needing to enter searches with exact case sensitivity.

Answer №1

Transform the variable this.result into lowercase.

RetrieveUserCourses() {
  let result = this.result.toLowerCase()
  return this.courses.filter(course => {
    return course.name.toLowerCase().includes(result);
  });
},
