I want to filter array if it contains a particular string. It works as shown below. But I am not sure how to solve it if there are multiple strings to match. For example - instead of skillText = "Entry Level"; if we have skillText = ["Entry Level", "Scientist", "Analyst"];

var myList = [{"Title":"Entry Level - Data Analyst","Location":"Boston"}, {"Title":"Entry Level3 -  Analyst","Location":"Delhi"}, {"Title":"Scientist","Location":"Boston"}];

skillText = "Entry Level";
result = myList.filter(function(v) {
    return v["Title"].indexOf(skillText) > -1;
  })
  
console.log(result);  

For exact match skillText.includes(v["Title"]) works but not sure how to do with partial matches.

CodePudding user response：

You can use the some function on arrays, it returns true if any of the items returns true from the callback

skillTexts = ["Entry Level", "Scientist"];
result = myList.filter(function(v) {
    return skillTexts.some(function(skill) {
        return v["Title"].includes(skill)
    });
})

This may be one possible solution to achieve the desired objective:

Code Snippet

const findMatches = (hayStack, needle) => (
  hayStack.filter(
    ({Title}) => (
      [].concat(
        needle
      ).some(
        skill => Title.includes(skill)
      )
    )
  )
);

const myList = [{"Title":"Entry Level - Data Analyst","Location":"Boston"}, {"Title":"Entry Level3 -  Analyst","Location":"Delhi"}, {"Title":"Scientist","Location":"Boston"}];

let skillText = 'Entry Level';
console.log('searching text: "Entry Level"\nfound: ', findMatches(myList, skillText));

skillText = ['Level', 'Analyst', 'Scientist'];
console.log('searching array', skillText.join(), '\nfound: ', findMatches(myList, skillText));

Explanation

• Use .filter to iterate over the array (hayStack)
• De-structure to directly access Title from the iterator
• To acccommodate needle (search-text being a string or an array), first use [].concat() to obtain an array (This is done per pilchard's comment in the question above)
• Use .some to iterate and find if any element is part of Title
