Understanding Assignment Operators
The assignment is a fundamental operation that assigns values to variables, constants, array elements, and more. This operation is performed using the = symbol.
let a; // Declare a variable `a`
const b = 26; // Define a constant `b` with the value `26`
a = 15; // Assign the value `15` to the variable `a`
console.log("a =", a, "b =", b);
a = []; // Assign an empty array to the variable `a`
a[0] = 5; // Assign the value `5` to the first element of the array `a`
console.log("Array:", a); // Print the array `a`
let a; // Declare a variable `a` const b = 26; // Define a constant `b` with the value `26` a = 15; // Assign the value `15` to the variable `a` console.log("a =", a, "b =", b); a = []; // Assign an empty array to the variable `a` a[0] = 5; // Assign the value `5` to the first element of the array `a` console.log("Array:", a); // Print the array `a`
Why Is This Important?
While the assignment operation is simple, it's essential to distinguish it from another operation called equal to, which we will describe later in this section.
This understanding is crucial because it helps you effectively work with variables, constants, and data in JavaScript.
