在Javascript中进行比较时如何避免分配? [英] How to avoid assignments while comparing in Javascript?

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

Lint it. There are tools that can automatically analyze your Javascript and catch common errors like this.
