JavaScript Strict Equality Operator is used to compare two operands and return true if both the value and type of operands are the same. Since type conversion is not done, so even if the value stored in operands is the same but their type is different the operation will return false.
Syntax:
a===b
Example 1: In this example, we will compare the value of the same data types.
JavaScript
let a = 2, b=2, c=3;
let d = {name:"Ram"};
let e = {name:"Ram"};
let f = e;
console.log(a===b);
console.log(a===c);
console.log(d===e);
console.log(f===e);
Output: Just like other comparisons when two objects are compared their reference is checked and true is only returned if the reference is the same.
true false false true
Example 2: In this example, we will use the strict equality operator on different data types.
JavaScript
let a = 2;
let b= "2";
let c = true;
let d = null;
let e = undefined;
console.log(a===b);
console.log(a===c);
console.log(d===e);
Output: Even though some values are the same but still false is returned as the data type is different.
false false false
