• I. Theory

  • 1. …
  • 2. Basic concepts of JavaScript
    • 2.1. Variables. Data types
      • 2.1.1. Variables. Primitive data types. Comments. Constants. Keywords var, const. Operator typeof
      • 2.1.2. Object Number
        • 2.1.2.1. Numeric data type Number. Conversion functions between numeric type and other types. Functions Number(), parseInt(), parseFloat()
        • 2.1.2.2. Functions that determine the current state of Number object. Functions isFinite(), isInteger(), isNaN(), isSafeInteger()
        • 2.1.2.3. Functions for representing the Number object in different notations. Functions toExponential(), toFixed(), toLocaleString(), toPrecision(), toString(), valueOf()
        • 2.1.2.4. Properties of Number object
    • 2.2. Operators
      • 2.2.1. Classification of operators
      • 2.2.2. Operators priority
      • 2.2.3. Special operators
    • 2.3. Control operators
      • 2.3.1. Conditional operator if-else
      • 2.3.2. Statement switch
      • 2.3.3. The concept of a loop. Loop statements for, while, do-while
      • 2.3.4. The for-in loop. Nested loops. Eternal loop
      • 2.3.5. Instructions break and continue in loop statements
    • 2.4. Arrays
      • 2.4.1. One-dimensional arrays. Creating an array. The length property. Array formation
      • 2.4.2. Two-dimensional arrays. Arrays within arrays. Three-dimensional arrays
      • 2.4.3. Task solving using one dimensional arrays. Examples
      • 2.4.4. Solving of tasks using two-dimensional arrays
    • 2.5. Methods for working with arrays
      • 2.5.1. Methods for working with arrays. The list. Method at(). Methods that define information about array as a whole: every(), some(), include()
      • 2.5.2. Methods that receive data from an array without changing the array itself: indexOf(), lastIndexOf(), find(), findIndex(), slice(), concat(), toString(), join()
      • 2.5.3. Methods that modify array. Part 1. Methods sort(), reverse(), forEach(), filter(), map(), copyWithin(), splice()
      • 2.5.4. Methods that modify array. Part 2. Methods pop(), push(), reduce(), reduceRight(), shift(), unshift(), fill()
