The assignment operator in JavaScript is used to store a value in a variable. The assignment operator is the equal sign (=).
Here is an example of how to use the assignment operator to store a value in a variable:
[dm_code_snippet background=”yes” background-mobile=”yes” slim=”no” line-numbers=”no” bg-color=”#abb8c3″ theme=”dark” language=”php” wrapped=”no” height=”” copy-text=”Copy Code” copy-confirmed=”Copied”]
let x; // Declare a variable named "x" x = 10; // Assign the value 10 to x
[/dm_code_snippet]
You can also use the assignment operator to assign a value to a variable when you declare it:
[dm_code_snippet background=”yes” background-mobile=”yes” slim=”no” line-numbers=”no” bg-color=”#abb8c3″ theme=”dark” language=”php” wrapped=”no” height=”” copy-text=”Copy Code” copy-confirmed=”Copied”]
let y = 20; // Declare a variable named "y" and assign it the value 20
[/dm_code_snippet]
You can also use the assignment operator to assign a value to a variable that has already been declared:
[dm_code_snippet background=”yes” background-mobile=”yes” slim=”no” line-numbers=”no” bg-color=”#abb8c3″ theme=”dark” language=”php” wrapped=”no” height=”” copy-text=”Copy Code” copy-confirmed=”Copied”]
let z; // Declare a variable named "z" z = 30; // Assign the value 30 to z z = 40; // Re-assign the value 40 to z
[/dm_code_snippet]
You can also use the assignment operator to assign a value to a variable that has already been declared and initialized:
[dm_code_snippet background=”yes” background-mobile=”yes” slim=”no” line-numbers=”no” bg-color=”#abb8c3″ theme=”dark” language=”php” wrapped=”no” height=”” copy-text=”Copy Code” copy-confirmed=”Copied”]
let a = 50; // Declare a variable named "a" and assign it the value 50 a = 60; // Re-assign the value 60 to a
[/dm_code_snippet]
You can also use the assignment operator to assign a value to a variable that has been declared using the const keyword:
[dm_code_snippet background=”yes” background-mobile=”yes” slim=”no” line-numbers=”no” bg-color=”#abb8c3″ theme=”dark” language=”php” wrapped=”no” height=”” copy-text=”Copy Code” copy-confirmed=”Copied”]
const b = 70; // Declare a constant named "b" and assign it the value 70
[/dm_code_snippet]
However, you cannot re-assign a value to a constant using the assignment operator. If you try to do so, you will get a TypeError.
[dm_code_snippet background=”yes” background-mobile=”yes” slim=”no” line-numbers=”no” bg-color=”#abb8c3″ theme=”dark” language=”php” wrapped=”no” height=”” copy-text=”Copy Code” copy-confirmed=”Copied”]
b = 80; // This will throw a TypeError because you cannot re-assign a value to a constant
[/dm_code_snippet]
You can also use the assignment operator to assign a value to multiple variables at the same time:
[dm_code_snippet background=”yes” background-mobile=”yes” slim=”no” line-numbers=”no” bg-color=”#abb8c3″ theme=”dark” language=”php” wrapped=”no” height=”” copy-text=”Copy Code” copy-confirmed=”Copied”]
let c = 10, d = 20, e = 30; // Declare three variables and assign them the values 10, 20, and 30, respectively
[/dm_code_snippet]
You can also use the assignment operator to assign a value to a variable that is the result of an expression:
[dm_code_snippet background=”yes” background-mobile=”yes” slim=”no” line-numbers=”no” bg-color=”#abb8c3″ theme=”dark” language=”php” wrapped=”no” height=”” copy-text=”Copy Code” copy-confirmed=”Copied”]
let f = (10 + 20) * 30; // Declare a variable named "f" and assign it the result of the expression (10 + 20) * 30
[/dm_code_snippet]
