How can you find out if a sub-string is present in a given string?myString.includes(subString)myString.find(subString)myString.has(subString)
Solution
To find out if a sub-string is present in a given string in JavaScript, you can use the includes() method. Here is a step-by-step guide:
- Define your string. For example:
let myString = "Hello, world!"; - Define the sub-string you want to find. For example:
let subString = "world"; - Use the
includes()method to check if the sub-string is in the string. For example:myString.includes(subString);
This will return true if the sub-string is found in the string, and false if it is not.
Note: The find() and has() methods you mentioned do not exist for strings in JavaScript.
