Question

Explore the array by locating elements based on the initial two letters of each word in the array

In the given array, I am looking to find the first letters in multiple words within the same matrix. It should search through each word and return in an array if found.

For example:

const data= [ 
      "the lions of teranga",
      "tiger woods",
      "The Truman Show",
      "Shutter Island",
      "The Gold Rush",
  ]
]

If it matches "sh", it should search through each word and return:

["Shutter Island", "The Truman Show"] but not The Gold Rush

If it matches "lions", it should search through each word and return:

["the lions of teranga"]

Answer №1

This solution utilizes a combination of forEach and RegEx to extract specific words.

const data= [ 
      "the lions of teranga",
      "tiger woods",
      "The Truman Show",
      "Shutter Island",
      "The Gold Rush",
  ]
  
const filteredData = []


data.forEach(sentence => {
    let words = sentence.split(" ")
    words.forEach((word,index) => {
      if(word.match(/^lions?\w/gi)) {
        filteredData.push(sentence)
      }
    })
    
})

console.log(filteredData)

let items = [ 
      "ocean waves",
      "mountain peaks",
      "The Great Gatsby",
      "Forest Greens",
      "The Grand Canyon",
  ]
searchTerm = "mountain"
let results = items.filter(item => {
    text = item.toLowerCase()
    if (text.match(searchTerm.toLowerCase())){
        return item
    }
})
console.log(results)

This filter function returns all items that contain the specified search term. It is versatile and can be used to filter by any word or character.

//your array of elements
const elements= [ 
      "the lions of teranga",
      "tiger woods",
      "The Truman Show",
      "Shutter Island",
      "The Gold Rush",
  ];
    //your keyword for search, if constant use const instead of var
    var keyword="sh";
    //making the search case insensitive
    keyword=keyword.toLowerCase()
    //using a for loop to iterate through each element
    for(var i=0;i<elements.length;i++)
    {
       //extracting the array of words
       var wordsArray=elements[i].match(/\b(\w+)\b/g);
       
       //using another for loop to iterate through each word
