javascript多级对象操作

如何编写接受injectionObject并修改currentObject的函数？如果我没有弄错的话，我相信这就是GraphQL的工作方式。我需要在纯JS中实现这个效果

    //Object to inject into current object
    const injectionObject = {
        pages: {
            about: {
                title: 'Changed About Page'
            }
        }
    }
    //Object that requires modification based on above object
    const currentObject = {
        pages: {
            home: {
                title: 'Home Page',
                description: 'This is the home page'
            },
            about: {
                title: 'About Page',
                description: 'This is the about page'
            }
        }
    }
    //output
    const outputObject = {
        pages: {
            home: {
                title: 'Home Page',
                description: 'This is the home page'
            },
            about: {
                title: 'Changed About Page', //Only this was affected
                description: 'This is the about page'
            }
        }
    }

您可以获取条目并更新属性或访问嵌套属性

const
更新=（目标，源）=>Object.entries（源）.forEach（[k，v]）=>{
if（v&&typeof v==='object'）更新（target[k]=target[k]|{}，v）；
else目标[k]=v；
}),
injectionObject={pages:{about:{title:'Changed about Page'}}}，
currentObject={pages:{home:{title:'home Page'，description:'这是主页'}，about:{title:'about Page'，description:'这是about页面'}}；
更新（currentObject、injectionObject）；
console.log（currentObject）
。作为控制台包装{最大高度：100%！重要；顶部：0；}
