What is the reason to choose the name let as a keyword

The keyword let was chosen because it originates from mathematical notation, where "let" is used to introduce new variables (for example, "let x = 5"). This term was adopted by several early programming languages such as Scheme and BASIC, establishing a tradition in computer science. JavaScript follows this convention by using let to declare variables with block scope, providing a modern alternative to var. The choice helps make the language more familiar to programmers coming from other languages and aligns with the mathematical practice of variable assignment.
