This is my unique text:
let x = "Learning new things every day!";
I am utilizing the substring() method to extract a specific part of it:
console.log(x.substring(9, 12));
Instead of the entire string, I only want the word 'new'.
let x = "learning something new today"
console.log(x.substring(17, 20));<script src="https://ajax.googleapis.com/ajax/libs/reactjs/2.5.4/react.min.js"></script>Can anyone assist me with this query?
Give this code a shot:
let phrase = "hello there world";
console.log(phrase.split(" ")[1]);
To efficiently search for a specific value within a string, consider splitting the string into an array of substrings and then iterating through each element to find the desired value:
var initialString = "Hello world from JavaScript";
var arrayOfWords = initialString.split(" ");
for (let j = 0; j < arrayOfWords.length; j++) {
if(arrayOfWords[j] == 'world') {
console.log(arrayOfWords[j]);
}
}
By using this approach, you won't need to manually specify which element in the array contains the target value as the code will handle the task automatically.
