Categorized request examples and articles tagged with [javascript-string-contains] keyword How do I check if a string contains a substring in JavaScript?
To check if a string contains a substring in JavaScript, use the string.includes(term, start) method, which checks if the string contains the substring. The first parameter is the string to search for, and the second optional parameter specifies the position from which to search. The string.includes() method is case-sensitive. Also, you can check if the string contains a substring by using a string.indexOf(term, start), which returns the index of the substring within the string instead of the boolean value returned by the string.includes(). In this JavaScript String Contains Substring example, we use the string.includes() to check if the substring is in the string. You can see more examples of searching for substrings in strings below, including using JavaScript Regular Expressions.
