To use the search method in TypeScript, you first need to create a string variable. For example:
let myString: string = "This is a sample string";
Once you have your string variable, you can use the search method to find a specific character or word within the string. The search method returns the index of the first occurrence of the specified character or word. For example:
let index: number = myString.search("sample");
In this example, the search method will return the index of the first occurrence of the word “sample” within the string. If the word is not found, the search method will return -1.
It is important to note that the search method is case-sensitive. If you want to perform a case-insensitive search, you can use the toLowerCase method to convert the string to lowercase before performing the search. For example:
let index: number = myString.toLowerCase().search("sample");
This will convert the string to lowercase and then perform the search, which will be case-insensitive.
In conclusion, the search method in TypeScript can be a powerful tool for finding specific characters or words within a string. By using this method, you can easily locate the information you need and manipulate it as necessary.
