Learn how to add space between words in JavaScript, with examples and explanations.
how to give space in javascript between words
To give space between words in JavaScript, you can use the space character which is represented by " ". Here is an example:
javascript Copy code
let firstName = "John";
let lastName = "Doe";
let fullName = firstName + " " + lastName; // full name with a space in between
console.log(fullName); // "John Doe"
In the example above, the space character is used to separate the firstName and lastName variables in the fullName variable.
What is the logical AND operator in JavaScript?
The logical AND operator in JavaScript is represented by &&. It is used to combine two or more conditions and returns true only if all conditions are true.
Here’s a simple example:
javascript Copy code
let a = true;
let b = false;
console.log(a && b); // Output: false
In this example, a is true, and b is false. The expression a && b evaluates to false because both conditions need to be true for the result to be true.
You can learn more about it in the MDN web docs.
What does parse float mean in JavaScript
parseFloat is a built-in JavaScript function that converts a string into a floating-point number (a number that can have decimals). It's useful when you want to take a string that represents a number and turn it into a format that you can perform calculations with.
Here's how it works:
javascript Copy code
let stringNumber = "3.14";
let floatNumber = parseFloat(stringNumber);
console.log(floatNumber); // Outputs: 3.14
console.log(typeof floatNumber); // Outputs: "number"
In this example, parseFloat takes the string "3.14" and converts it to the number 3.14. If the string doesn't start with a number, it will return NaN (which means "Not-a-Number").
For more information, you can check the MDN documentation on parseFloat.
what are break statements in javascript
In JavaScript, a break statement is used to stop the execution of a loop or switch statement. When the break statement is reached, the program will exit the loop or switch and continue with the next line of code after it.
Here’s a simple example with a loop:
javascript Copy code
for (let i = 0; i < 10; i++) {
if (i === 5) {
break; // Exit the loop when i is 5
}
console.log(i);
}
In this example, the loop prints numbers from 0 to 4. When i becomes 5, the break statement is executed, and the loop ends.
You can learn more about break statements in JavaScript on MDN Web Docs.
what does .push mean ?
In JavaScript, .push is a method used to add one or more elements to the end of an array. It modifies the original array and returns the new length of the array.
Here's a simple example:
let fruits = ['apple', 'banana']; fruits.push('orange'); // Adds 'orange' to the end of the array console.log(fruits); // Output: ['apple', 'banana', 'orange']
You can find more information about the .push method in the MDN documentation.
