严格不等 Strict Inequality Operator 严格不相等运算符(!==)与全等运算符是相反的。 严格不相等运算符不会转换值的数据类型。 3 !== 3 // false 3 !== '3' // true; 4 !== 3 // true; 1. 2. 3. 大于Greater Than Operator 使用大于运算符(>)来比较两个数字。 如果大于运算符左边的数字大于右...

5. Greater Than OperatorThe greater than operator > returnstrue if the value on the left is greater than the value on the right. false if the value on the left isn't greater than the value on the right.For example,// left operand is greater console.log(3 > 2); // true // both...
Example of JavaScript Greater than(>) operator The following function first evaluates if the condition (num > 50) evaluates to true converting num to a number if necessary. If it does, it returns the statement between the curly braces ("Over 50"). If it doesn’t, it checks if the next...
10) 关系运算符(Relational operator [rɪ'leɪʃənl]) 1. 赋值运算符(Assignment operators) 一个赋值运算符将它右边操作数的值赋给它左边的操作数。 最简单的赋值运算符是等于(=),它将右边的操作数值赋给左边的操作数。那么 x = y 就是将 y 的值赋给 x。
For the condition of the JavaScript ternary operator we use the less-than operator (<) to see if “a” is less than30. If “a” is less than30, the “b” variable will be assigned the text “Was less than 30“. If “b” is greater than or equal to30, the “b” variable will...
“Expected an operator and instead saw ‘{a}’.”:“需要用一个符号来代替’{a}’”, “Unexpected space after ‘{a}’.”:“在’{a}’之后不能出现空格”, “Unexpected space before ‘{a}’.”:“在’{a}’之前不能出现空格”, “Bad line breaking before ‘{a}’.”:“在’{a}’之前错...

Greater Than Operator (>) JavaScript’s greater than operator (>) is the opposite of the less-than operator. Therefore, this comparison operator will return true when the left-side operand is greater than the right side. If the values are equal, then the greater than operator returns false....
