How to find specific words in an array with JavaScript?


To find specific words in an array, you can use includes(). We have the following array −

var sentence = ["My Name is John Smith. My Favourite Subject is JavaScript. I live in US. I like Hockey"];

Now, the following is an array having the words we need to search in the above “sentence” array −

var keywords = ["John", "AUS", "JavaScript", "Hockey"];

Example

Following is the code −

var keywords = ["John", "AUS", "JavaScript", "Hockey"];
var sentence = ["My Name is John Smith. My Favourite Subject is JavaScript. I live in US. I like Hockey"];
const matched = [];
for (var index = 0; index < sentence.length; index++) {
   for (var outerIndex = 0; outerIndex < keywords.length; outerIndex++) {
      if (sentence[index].includes(keywords[outerIndex])) {
         matched.push(keywords[outerIndex]);
      }
   }
}
console.log("The matched keywords are==");
console.log(matched);

To run the above program, you need to use the following command −

node fileName.js.

Here, my file name is demo226.js.

Output

The output is as follows −

PS C:\Users\Amit\JavaScript-code> node demo226.js
The matched keywords are==
[ 'John', 'JavaScript', 'Hockey' ]
