在Javascript中进行比较时如何避免分配?

本文介绍了在Javascript中进行比较时如何避免分配?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我试图将变量与值进行比较，并意外地使用'='代替了'=='，因此代码看起来像这样:

I was trying to compare a variable to a value and accidently ended up using '=' in place of '==' hence the code looked like:

var test = 1; if(test = 2) { console.log(test); }

代替:

var test = 1; if(test == 2) { console.log(test); }

我假设已将值成功分配给变量，因此条件返回true，并执行了 console.log().我的假设正确吗?除了 Yoda条件参考

I assume the value was successfully assigned to the variable , hence the condition returned truthy and console.log() was executed. Is my assumption correct? What is a good coding practice to avoid such mistakes besides Yoda Condition reference
