The ≣ symbol, officially known in Unicode as "Strictly Equivalent To," features four horizontal parallel lines. In mathematics and formal logic, it denotes an absolute equivalence between two expressions, meaning they are identical in all possible contexts. Outside of math equations, web designers and developers occasionally use it as a stylized alternative to the standard three-line "hamburger menu" icon.

In Programming
In mathematical markup languages, this symbol expresses that two objects are identical in all contexts, rather than just equal in value. Modern programming languages rarely use this exact Unicode character in code, typically relying on '===' for strict equality operations.
