How to Check If Character is Double Quote Javascript

In JavaScript, you can check if a character is a double quote (`”`) by using a simple comparison.

Here are a Few Ways to Check If Character is Double Quote Javascript

1. Using `===` Comparison

You can check if a character is a double quote by comparing it directly:

javascript

let char = ‘”‘;
if (char === ‘”‘) {
console.log(“The character is a double quote.”);
} else {
console.log(“The character is not a double quote.”);
}

 2. Using `.includes()` for Strings

If you have a string and want to check if it contains a double quote, you can use the `.includes()` method:

javascript

let str = ‘He said, “Hello!”‘;
if (str.includes(‘”‘)) {
console.log(“The string contains a double quote.”);
} else {
console.log(“The string does not contain a double quote.”);
}

3. Using ASCII or Unicode

You can also use the ASCII code for double quotes (`34`) or Unicode (`\u0022`) if you prefer:

javascript

let char = ‘”‘;
if (char.charCodeAt(0) === 34) {
console.log(“The character is a double quote.”);
}

Or using Unicode:

javascript

if (char === ‘\u0022’) {
console.log(“The character is a double quote.”);
}
