Flatten a multi-dimensional object with separators.. Latest version: 0.0.1, last published: 7 years ago. Start using flatten-object-js in your project by running `npm i flatten-object-js`. There are no other projects in the npm registry using flatten-obj
This function is strict: "depth" must be a non-negative integer and "obj" must be a non-null object with at least "depth" levels of nesting under all keys. flattenIter(obj, depth, func) This is similar toflattenObjectexcept that instead of returning an array, this function invokesfunc(...
Object.assign() 可以使用Object.assign()来实现浅拷贝,因为Object.assign()的目的就是将一个或多个源对象复制给目标对象,并且返回修改后的对象。 代码语言:javascript 复制 functionmyShadowCopy(target){returnObject.assign({},target);}constobj={name:'clz',job:{type:'Coder'}};constshadowCopyObj=myShadowC...
flattenObjSass( obj, prefix = "$", transform = (prop, val) => val )obj: The object that will be transformed prefix = String prepended to every "property", default is $ to mimic Sass variables transform: you can manipulate the value, the key is passed to check purposes.Example:...
