Check If String Contains Exact Match in JavaScript

To Check If String Contains an Exact Match in JavaScript, we use 2 methods where we use two main JavaScript built-in functions. One is split() and second is RegExp method.

Code Explanations:

• Here we create variables to store some strings and words first.
• After that, we split all the words from the complete sentence using var words = sentence.split(" ");
• At the last, we take all the words from sentences using the loop and compare them with the given string.

for (var i = 0; i < words.length; ++i) {
if(words[i] === compare) {
alert("found " + compare);
break;
}
}

• Now you can call the created function with required parameters.

Method-2

Code Explanations:

• In this method, first, we replace all the spaces and other slashes from the string using replace() JS function.
  • replace(/[-\/\\^$*+?.()|[\]{}]/g, '\\$&')
• In the second step, we use regExp or regular expression to check the exact match. Also, we use the above replace functionality inside the regExp object.
  • return new RegExp(\\b${escapeRegExpMatch(match)}\\b).test(str)
• At last, we match the string with a sentence using the created function.
  • isExactMatch(sentence, keyword)
