Check if string contains specific character

Given a string and character, check if the string contains specified character using JavaScript.

Solution

To check if a string contains a given character using JavaScript, we can use String.includes() method. call includes() method on the string, and pass the specific character (as a string) as argument. includes() returns true if the string contains the specified character, or false if the string does not contain the character.

Program

1. given string is str and character is ch. check if string str contains ch

str = "hello world";
ch = "w";

if ( str.includes(ch) ) {
    console.log('string contains specified character');
} else {
    console.log('string does not contain specified character');
}
