// JavaScript - Check If a String Contains any Whitespace Characters

// 1. Using Regular Expressions

{

const s = "Hello world";

const hasSpace = /\s/.test(s);

console.log(hasSpace);

}

// 2. Using String.prototype.includes() Method

{

const s = "Helloworld";

const hasSpace = s.includes(" ");

console.log(hasSpace);

}

// 3. Using String.prototype.match() Method

{

const s = "Hello world";

const hasSpace = s.match(/\s/) !== null;

console.log(hasSpace);

}

// 4. Using String.prototype.search() Method

{

const s = "Hello world";

const hasSpace = s.search(/\s/) !== -1;

console.log(hasSpace);

}

// 5. Using a for Loop

{

const s = "HelloWorld";

let hasSpace = false;

for (const char of s) {

if (/\s/.test(char)) {

hasSpace = true;

break;

}

}

console.log(hasSpace);

}

// 6. Using Array.prototype.some() Method

{

const s = "Hello World";

const hasSpace = [...s].some((char) => /\s/.test(char));

console.log(hasSpace);

}

// 7. Using Array.prototype.filter() Method

{

const s = "HelloWorld";

const hasSpace = s.split("").filter((char) => /\s/.test(char)).length > 0;

console.log(hasSpace);

}

// Using javascript sets

{

const s = "Hello world";

const set = new Set([" ", "\t", "\n", "\r"]);

const hasSpace = [...s].some((char) => set.has(char));

console.log(hasSpace)

}
