๐ฅ LAST-DAY INTERVIEW TIPS
โข Practice coding problems on platforms like LeetCode or Codewars.
โข Be prepared to explain your thought process during coding challenges.
โข Review common algorithms and data structures.String: Represents text (e.g., "Hello World")
โ Number: Represents numeric values (e.g., 42, 3.14)
โ Boolean: Represents true or false values (true, false)
โ Undefined: A variable that has been declared but not assigned a value.
โ Null: Represents an intentional absence of any object value.
โ Symbol: A unique and immutable primitive value (ES6).
โข Reference Types:
โ Object: Collections of key-value pairs.
โ Array: An ordered list of values.
โ Function: A callable object.
4๏ธโฃ Variables
โข Declaration Keywords:
โ var: Function-scoped or globally scoped.
โ let: Block-scoped and can be reassigned.
โ const: Block-scoped and cannot be reassigned.
5๏ธโฃ Control Structures
โข Conditional Statements:
if (condition) {
// code to execute if condition is true
} else {
// code to execute if condition is false
}
โข Switch Statement:
switch (expression) {
case value1:
// code block
break;
case value2:
// code block
break;
default:
// default code block
}
โข Loops:
โ For Loop:
for (let i = 0; i < array.length; i++) {
// code to execute
}
โข While Loop:
while (condition) {
// code to execute
}
6๏ธโฃ Functions
โข Function Declaration:
function functionName(parameters) {
// code to execute
return value;
}
โข Arrow Functions (ES6):
const functionName = (parameters) => {
// code to execute
return value;
};
7๏ธโฃ Objects and Arrays
โข Creating Objects:
const person = {
name: "John",
age: 30,
greet: function() {
console.log("Hello!");
}
};
โข Accessing Object Properties:
console.log(person.name); // Dot notation
console.log(person['age']); // Bracket notation
โข Arrays:
const fruits = ["apple", "banana", "cherry"];
console.log(fruits[0]); // Accessing first element
8๏ธโฃ ES6 Features
โข Template Literals:
const greeting = Hello, ${name}!;
โข Destructuring Assignment:
const { name, age } = person;
โข Spread Operator:
const newArray = [...oldArray, newItem];
9๏ธโฃ Asynchronous JavaScript
โข Callbacks:
function fetchData(callback) {
// Simulate async operation
setTimeout(() => {
callback("Data received");
}, 1000);
}
โข Promises:
const promise = new Promise((resolve, reject) => {
// Async operation
if (success) {
resolve("Success!");
} else {
reject("Error!");
}
});
โข Async/Await:
async function fetchData() {
try {
const result = await promise;
console.log(result);
} catch (error) {
console.error(error);
}
}
๐ Best Practices
โข Use let and const instead of var for better scope control.
โข Keep your functions small and focused on a single task.
โข Use meaningful variable and function names.
โข Comment your code for clarity.
โข Avoid global variables to prevent conflicts.
