Data is lot more than that, around 1.5 MB coming from a JSON file hosted online, this is just sample, I have to filter the jobs on the basis of location, skill, experience.

What I thought of to add everything to the state then preprocess the data in the 3 diff array with the following format

      {
        value: jobData.xxx,
        label: jobData.xxx
      }

Push the data in react-select, get from that and use a filter for the whole state and display the result in a nice UI.

The problem here is data is really huge, and no option to get chunks from backend, I have to use the full data at once.

My questions are:-

• How to store the data skill, location and exp segregate in diff array without the duplicated elements, I tried with a map, duplicated element are coming. Iterating through the whole array again to check if it's not there would not be efficient?
• Is there a better way you all propose to do it?

Thanks

Edit-1

So basically what i want 3 json object

 var skill = {
        value: jobData.skills,
        label: jobData.skills
      };
      var location = {
        value: jobData.location,
        label: jobData.location
      };
      var experience = {
        value: jobData.experience,
        label: jobData.experience
      };

pushed in three array:

 var skillList=[];
    var locationList=[];
    var experienceList=[];

Which will be inturn set in react state

Edit-2

This is the whole code:

import React from "react";
import Style from "./Landing.module.scss";
import JobImage from "./2663543.jpg";
import Select from "react-select";
class LandingPage extends React.Component {
  state = {
    data: [
    //the data mentiond above
    ],
    skills: [],
    location: [],
    experience: []
  };

  componentDidMount() {

    var skillList=[];
    var locationList=[];
    var experienceList=[];


    this.state.data.map(jobData => {
      var skill = {
        value: jobData.skills,
        label: jobData.skills
      };
      var location = {
        value: jobData.location,
        label: jobData.location
      };
      var experience = {
        value: jobData.experience,
        label: jobData.experience
      };
    });


  }

  render() {
    return (
      <>
        <div className={Style.bigHead}>
          <div className={Style.bigImage}>
            <img src={JobImage} alt="Job Image"></img>
          </div>
          <div className={Style.filters}>
            <Select
              isMulti
              name="location"
              options={this.state.location}
              className="basic-multi-select"
              classNamePrefix="select"
            />
             <Select
              isMulti
              name="experience"
              options={this.state.experience}
              className="basic-multi-select"
              classNamePrefix="select"
            />
             <Select
              isMulti
              name="skill"
              options={this.state.skills}
              className="basic-multi-select"
              classNamePrefix="select"
            />
          </div>
        </div>
      </>
    );
  }
}

export default LandingPage;
