A function definition is an executable expression, whose value has typefunction. When Lua pre-compiles a chunk, all its function bodies are pre-compiled too. Then, whenever Lua executes the function definition, the function isinstantiated(orclosed). This function instance (orclosure) is the fina...

The only requirement in any function call is that the expression before the parentheses must evaluate to a function address. This means that a function can be called through any function-pointer expression.ExampleThis example illustrates function calls called from a switch statement:...

This topic describes how to dot index into temporary variables created by function calls. Atemporary variableis created when the result of a function call is used as an intermediate variable in a larger expression. The result of the function call in the expression is temporary because the variabl...

In this context,primary-expressionis the first operand, andexpression-list, a possibly empty list of arguments, is the second operand. The function-call operator is used for operations that require a number of parameters. This works becauseexpression-listis a list instead of a single operand. Th...
error: #59: function call is not allowed in a constant expression This is an similar example of the code: const sam_abc xy_settings = {function_yz(), 111, 250 }; - sam_abc is a struct - function_yz() is the function which causes the error ...
当我们忘记从函数中返回值时,会产生"Expected an assignment or function call and instead saw an expression"错误。为了解决该错误,确保显式地使用return语句或使用箭头函数隐式返回。 react-expected-assignment-or-function-call.png 下面有两个示例来展示错误是如何产生的。
