Jan 6, 2023 · Difference Between == & === in JavaScript In JavaScript, equality operators are used to compare values. However, == (double equals) and === (triple equals) behave differently: == (Loose Equality): Converts values to the same data type before comparing (type coercion).=== (Strict Equality): Compares both value and data type, without converti

Mar 12, 2020 · You may have seen double and triple equals signs in JavaScript. But what do they mean? Well in short: == inherently converts type and === does not convert type. Double …

Mar 6, 2025 · JavaScript provides three different value-comparison operations: Which operation you choose depends on what sort of comparison you are looking to perform. Briefly: Triple equals (===) will do the same comparison as double equals (including the special handling for NaN, -0, and +0) but without type conversion; if the types differ, false is returned.

May 19, 2013 · It depends on the use case. Triple equals is to check for identicality; in other words, not only equivalent, but the same type. Here's a good reference

Nov 29, 2015 · What's the difference between double (==) and triple (===) equals operators in Javascript. In this post i explain how triple equals different from double equals.

Feb 16, 2023 · In this blog post, we’ll explore the difference between == and === in JavaScript and why it’s important to use the triple equal operator. The Double Equal (==) Operator. The double equal operator is used to compare two values to see if they are equal. If the two values are equal, the operator returns true.

The double equals (==) operator checks if two values are equal after implicit type coercion. This means it may convert the types to compare them. The triple equals (===) operator checks if two values are equal without type conversion, requiring equality in both value and type.

JavaScript has an equality operator (double equals ==) and an identity operator (triple equals ===). Though they look similar, they're drastically different from one another. In this post we'll talk about the difference between them as well as recommend which one you should use.

Nov 17, 2017 · JavaScript has two visually similar, yet very different, ways to test equality. You can test equality with == or ===. Here are the differences: When using triple equals === in JavaScript, we are testing for strict equality. This means both the type and the value we are comparing have to be the same.

Aug 5, 2021 · In JavaScript, the comparison happens in two ways. Comparison with type; Comparison with values; So, what’s the difference between == and ===? One simple answer 👇. The double equals first converts the type of the operand and then compares them with values. While the triple equals compares the values without changing the type of the operand.
