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.”);
}
