问题 I need to find and replace values in my object when they match a regular expression (e.g. **myVar**); The object that I need to loop through is user defined and structure varies.

问题 I am trying to have search for Underscore equivalent for Lodash _.get and _.has , where it is able to directly access the existence and value of nested object value without the need of checking the existence of its parents.

If I open multiple browser sessions with different users, it gets too buggy. composition post startedTyping will call back-end service and Vuex store it. In the view I get a list of who-is-typing, loop through it and display it on a condition. stoppedTyping will remove the previous value from the store. EDIT In the view: <template v-for="(typer,key) in typings"> <p v-if="condition(typer)" v-bind:key="key"> {{typer.name}} </p> </template> 来源：
