我有2个功能具有相同的逻辑(例如:在控制台中打印多个串联的元素),但具有一种特殊性。简单的方法是在参数中指定特异性,例如:
function baseLogic (specific, general) {
// ... many processes before here
if(specific == "info") console.info(general)
if(specific == "warn") console.warn(general)
}
// Calls
baseLogic("info", "foo")
baseLogic("warn", "bar")
但是,我想使用函数而不是像这样处理这种特异性:
function baseLogic (specific, general) {
// ... many processes before here
if(specific == "info") console.info(general)
if(specific == "warn") console.warn(general)
}
function info(general) {
baseLogic("info", general)
}
function warn(general) {
baseLogic("warn", general)
}
// Calls
info("foo")
warn("foo")
问题是,例如,当我想添加/删除参数时,我需要在各处添加/删除参数
有什么方法可以做得更好?
类似这样的东西:
function baseLogic (specific, general) {
// ... many processes before here
if(specific == "info") console.info(general)
if(specific == "warn") console.warn(general)
}
info = baseLogic("info")
warn = baseLogic("warn")
// Calls
info("foo")
warn("bar")
谢谢!

也许您正在寻找的是 curry函数:
// no curry
const sum = (a, b) => a + b
// no curry usage
sum(3, 4)
// curry
const sum = a => b => a + b
// curry usage
sum (2)(1);
